  • The Mesolithic of Atlantic Coastal Spain – a comparison with the
           Middle Ebro Basin

    • Authors: aneveu
      Geoffrey A. CLARK & C. Michael BARTON
      This paper compares current evidence for Mesolithic adaptations along the north Spanish coast from Galicia in the west to the Basque Country in the east. Significant questions and issues pertinent to Mesolithic research are reviewed, followed by a brief discussion of advances in method and theory over the past 25 years. Cantabria, País Vasco, and Galicia are compared with each other and en bloc with evidence from the middle Ebro over the 12-6 ka BP interval considered to bracket the transition between foraging and domestication economies. Marked differences in the time-space grid, geology, and the resolution of the data hinder these comparisons. A radiocarbon database totaling 610 dates is compiled, cleaned, filtered and analyzed for each region individually using summed calibrated date probability distribution (SPD) curves as a proxy for population density fluctuations over time. Regional curves are then compared with each other and with a global model.Lire la suite

  • New dalmanitid trilobite taxa from the Lower Devonian of Argentina:
           comments on spinosity in endemic taxa from southern high paleolatitudes

    • Authors: aneveu
      Enrique A. RANDOLFE, Juan José RUSTÁN & Arnaud BIGNON
      Three new Lower Devonian dalmanitid trilobite taxa are recognized from the Talacasto Formation in the Precordillera Basin, Argentina, which includes two monospecific genera (Ivanites leonorae n. gen., n. sp. and Aguaditaspis mediaspina n. gen., n. sp.), and one additional new genus and species left in open nomenclature. These taxa combine characters of the subfamilies Dalmanitinae Vogdes, 1890 and Synphoriinae Delo, 1935, challenging their taxonomic distinction. Forty percent of the dalmanitids from high paleolatitudinal basins from southwestern Gondwana (Malvinokaffric) exhibit non-homologous dorsal spinosity. Aguaditaspis mediaspina n. gen., n. sp. shares similar spines with Trypaulites calypso (Hall, 1861). The unnamed new genus resembles the spinosity of endemic Malvinokaffric dalmanitids, like Dalmanitoides Delo, 1935 and Fenestraspis Braniša & Vaněk, 1973. Considered defensive, the recorded spinosity along with putative sublethal-attack marks, suggest higher predation pressure than previously thought at high paleolatitudes. This evidence is in accordance with some hypothesis on rising predation pressure in the mid-Paleozoic marine ecosystems.Lire la suite

  • Phylogenetic signal in characters from Aristotle’s History of

    • Authors: aneveu
      Michel LAURIN & Marcel HUMAR
      The influential Greek philosopher Aristotle (384-322 BCE) is almost unanimously acclaimed as the founder of zoology. There is a consensus that he was interested in attributes of animals, but whether or not he tried to develop a zoological taxonomy remains controversial. Fürst von Lieven and Humar compiled a data matrix from Aristotle’s Historia animalium and showed, through a parsimony analysis published in 2008, that these data produced a hierarchy that matched several taxa recognized by Aristotle. However, their analysis leaves some questions unanswered because random data can sometimes yield fairly resolved trees. In this study, we update the scores of many cells and add four new characters to the data matrix (147 taxa scored for 161 characters) and quote passages from Aristotle’s Historia animalium to justify these changes. We confirm the presence of a phylogenetic signal in these data through a test using skewness in length distribution of a million random trees, which shows that many of the characters discussed by Aristotle were systematically relevant. Our parsimony analyses on the updated matrix recover far more trees than reported by Fürst von Lieven and Humar, but their consensus includes many taxa that Aristotle recognized and apparently named for the first time, such as selachē (selachians) and dithyra (Bivalvia Linnaeus, 1758). This study suggests that even though taxonomy was obviously not Aristotle’s chief interest in Historia animalium, it was probably among his secondary interests. These results may pave the way for further taxonomic studies in Aristotle’s zoological writings in general. Despite being almost peripheral to Aristotle’s writings, his taxonomic contributions are clearly major achievements.Lire la suite

           member of the Plectograptus lineage from the Silurian of Baltica, Poland

    • Authors: aneveu
      Anna KOZŁOWSKA
      Most upper Homerian and Ludfordian retiolitines have a tubarium with hexagonal meshes and a zigzag pattern in the middle part of their lateral walls, a shallow ancora umbrella, and a free nema. Hoffmanigraptus varsoviensis n. gen., n. sp. is described from isolated, three-dimensional material, from the upper part of the Colonograptus praedeubeli Biozone (upper Homerian, Silurian) of Poland, Baltica, and represents one of the earliest forms with this construction. This type of tubarium is represented by the upper Homerian Doliograptus Lenz & Kozłowska-Dawidziuk, 2002 and Spinograptus Bouček & Münch, 1952, differing from Hoffmanigraptus n. gen. mainly in larger proximal lateral orifices, pattern of clathrial lists on lateral walls, as well as size and shape of tubaria. Hoffmanigraptus n. gen. has a tubarium widening medially, tapering towards the distal end and forming a finite tubarium, with a possible three-vaned nematularium. Flattened specimens Plectograptus? ovatus Kozłowska, Lenz & Štorch, 2001 and Plectograptus? karlsteinensis Kozłowska, Lenz & Štorch, 2001, preserved on a rock surface from the Barrandian area are assigned to the new genus. They are of the same upper Homerian age, and show the main features of the new form. Hoffmanigraptus n. gen. is regarded as an early member of the Plectograptus clade.Lire la suite

  • The end of the Ice Age in southern Europe: Iberian images in the
           Palaeolithic to Post-Palaeolithic transition

    • Authors: aneveu
      Primitiva BUENO RAMÍREZ & Rodrigo de BALBÍN BEHRMANN
      The documentation of Palaeolithic art in the open air, together with direct dates for parietal art and the study of territories marked by the last hunter groups in southern Europe, supports new interpretations of Palaeolithic art and its continuity in the early Holocene. We provide updated information about the graphic representations in that time of transition, grouped under the term Style V. We also reflect on the chronological framework of some themes and techniques for which dates are available, from the Upper Palaeolithic to the Neolithic. These topics reveal the strength of the Palaeolithic background in more recent versions of prehistoric art, especially the schematic art associated with the first farmers. These new considerations are added to the presence of ­Palaeolithic and Post-Palaeolithic art throughout Europe and all over the world, which shows how symbols are social traits of communication associated with human groups. The study of con­nections through these archaeological items, with their undeniable materiality, is a future challenge that will ­undoubtedly produce interesting results.Lire la suite

  • A comparison of aleurone cells in centenarian African and contemporary
           barley seeds to identify the geographic origin

    • Authors: aneveu
      Claudio MILANESI, Rita VIGNANI, Monica SCALI, Claudia FALERI, Matteo DELLE DONNE, Mauro CRESTI & Lorenzo COSTANTINI
      Barley (Hordeum vulgare L.) is one of the main domesticated cereals. For this reason, barley seeds have been found in numerous archaeological sites, and since the mid-19th century have been available in numerous natural museum collections. About a hundred years ago samples were collected in the African countries of Eritrea and Cyrenaica (now Libya), and have been preserved as ex-situ in the museum collection “L’Orientale” of the University of Naples. The varieties of contemporary barley selected for comparative analysis were grown in Tuscany and are used in the production of craft beer. To ascertain their vitality, the ancient and contemporary seeds were placed in Petri dishes to hydrate under a sterile hood at room temperature after a sterilization procedure. Morphological and ultrastructural observations performed on the aleurone cells of the ancient samples presented vital cells. The extraction and purification of DNA from seeds produced results while the genotype comparison of ancient and contemporary barley varieties enabled the construction of a dendrogram of similarity, useful in describing barley from museum genetic heritage collections and in providing a molecular imprint of extant varieties.Lire la suite

  • Between two worlds: Cova Eirós and the Middle-Upper Palaeolithic
           transition in NW Iberia

    • Authors: aneveu
      Iberia, a natural cul-de-sac peninsula, plays a major role in the study of the Neanderthals demise and its eventual relationship with the spread of Anatomically Modern Humans (AMH) in Europe. The site of Cova Eirós (Galicia, Spain), located in NW Iberia, contains Middle and Upper Palaeolithic levels, based on the cultural remains recovered at the site. No human remains directly associated with those levels were discovered yet. The available radiocarbon dates from the levels 2 (c. 35 ka cal BP, Early Upper Paleolithic) and 3 (c. 41 ka cal BP, Late Middle Paleolithic), point to a late survival of Neanderthal groups in North Iberia and to a relative quick arrival of the AMH, c. 35-36 ka cal BP, with respect to other territories of the Iberian Peninsula. The archaeological record shows clear differences between the Middle and the Upper Palaeolithic occupations, regarding raw-material acquisition, lithic technology and subsistence strategies. The location of Cova Eirós in the westernmost margin of the Cantabrian Rim and in the Atlantic Façade, makes this site a key place to understand the spread of the first AMH and the progressive demise of Neanderthal populations.Lire la suite

      Une relecture de l’ensemble lithique de La Belle-Roche (Sprimont, Belgique), attribué au Paléolithique inférieur, est proposée à travers son étude pétroarchéologique. Cette étude a été conduite selon les grilles d’analyse développées ces dernières années en France. Si le caractère anthropique de certains objets ne laisse pas grand place au doute, leur mise en place dans le gisement demeure problématique. La lecture taphonomique des objets permet de s’interroger sur l’origine géologique de l’ensemble archéologique, l’âge de cette série et au-delà, de questionner la notion même de site : activités des préhistoriques ou construction de préhistorien ?Lire la suite

  • Garm Roud 2, Iran: bladelet production and cultural features of a key
           Upper Palaeolithic site south of the Caspian Sea

    • Authors: aneveu
      For more than twenty years, Iran has focused a great deal of research on the emergence and development of Upper Palaeolithic industries. South of the Caspian Sea, the site of Garm Roud 2, dated to 33878 ± 3300 Cal BP, is one of the few sites, with Mirak, to have yielded stratified evidence of occupation during this period. This paper presents the results of the typo-technological analysis of the lithic assemblage collected during the 2006 to 2008 excavation campaigns. The focus here is on a production of straight and twisted bladelets. Very few similarities have appeared between this assemblage and those from sites in the Zagros and the rest of Iran, which are generally older (about 35 to 40 000 Cal BP). Garm Roud 2 yields original evidence and may be seen as a key site for understanding Upper Palaeolithic technocomplexes and the development of bladelet production in this area.Lire la suite

  • New sperm whale remains from the late Miocene of the North Sea and a
           revised family attribution for the small crown physeteroid Thalassocetus
           Abel, 1905

    • Authors: aneveu
      Apolline ALFSEN, Mark BOSSELAERS & Olivier LAMBERT
      In spite of a continuously expanding physeteroid fossil record, our understanding of the origin and early radiation of the two modern sperm whale families Kogiidae Gill, 1871 (including the pygmy and dwarf sperm whales, Kogia spp.) and Physeteridae Gray, 1821 (including the great sperm whale, Physeter Linnaeus, 1758) remains limited, especially due to the poorly resolved phylogenetic relationships of a number of extinct species. Among those, based on fragmentary cranial material from the late early to middle Miocene of Antwerp (Belgium, North Sea basin), the small-sized Thalassocetus antwerpiensis Abel, 1905 has been recognized for some time as the earliest branching kogiid. The discovery of a new diminutive physeteroid cranium from the late Miocene (Tortonian) of Antwerp leads to the description and comparison of a close relative of T. antwerpiensis. Thanks to the relatively young ontogenetic stage of this new specimen, the highly modified plate-like bones making the floor of its supracranial basin could be individually removed, a fact that greatly helped deciphering their identity and geometry. Close morphological similarities with T. antwerpiensis allow for the reassessment of several facial structures in the latter; the most important reinterpretation is the one of a crest-like structure, previously identified as a sagittal facial crest, typical for kogiids, and here revised as the left posterolateral wall of the supracranial basin, comprised of the left nasal (lost in kogiids for which the postnarial region is known) and the left maxilla. Implemented in a phylogenetic analysis, the new anatomical interpretations result in the new Belgian specimen and T. antwerpiensis being recovered as sister-groups in the family Physeteridae. Consequently, the geologically oldest kogiids are now dated from the Tortonian, further extending the ghost lineage separating these early late Miocene kogiid records from the estimated latest Oligocene to earliest Miocene divergence of kogiids and physeterids.Lire la suite

  • De l’utilisation en percussion lancée d’éclats bruts massifs dans
           les activités de boucherie et travail du bois : le niveau moustérien de
           la Doline de Cantalouette 2 (Dordogne, France)

    • Authors: fsissi
      Laurence BOURGUIGNON, Ignacio CLEMENTE CONTE, Millán Mozota HOLGUERAS & Frédéric BLASER
      Le niveau moustérien de la Doline de Cantalouette 2, d’âge moyen de 60 000 ans est remarquable par sa richesse, sa composition et sa structuration récurrente des activités dans l’espace (Bourguignon et al. 2008). Il livre également une gamme d’instruments lithiques utilisés en percussion lancée. Outre une panoplie importante des percuteurs de taille (sur galets de quartz, éclats ou nucléus de silex), des éclats massifs en silex ont également été utilisés selon ce mode d’action pour des opérations de traitement de matériaux périssables tels les carcasses animales ou les végétaux. C’est exclusivement sur ces derniers modes de fonctionnement que nous orientons notre article. Les activités de production de ce Moustérien récent participent essentiellement d’un débitage algorithmique mettant en œuvre des séries unipolaires récurrentes, obtenues selon des plans de fracturation subparallèles aux dépens d’une ou de plusieurs surfaces. Des éclats épais, présentant souvent une asymétrie latérale sont obtenus à partir d’un ou plusieurs plans de frappe circonscrits (opposés ou perpendiculaires) et très rarement aménagés. Plus rarement, un débitage Levallois à éclat préférentiel, orienté vers une exportation des produits est également mis en œuvre. La production principale est quasi exclusivement réalisée pour une utilisation immédiate des éclats, distante du poste de taille, avec ou sans aménagement des parties actives et préhensives par la retouche (Bourguignon et al. 2008). C’est parmi cette production qu’une sélection d’éclats massifs aisément préhensibles à mains nues, souvent issus des premières étapes de la chaîne opératoire (corticaux), s’opère pour leur utilisation en percussion lancée. Sur la base d’une sélection macroscopique de tranchants (souvent bruts) présentant des stigmates d’écrasement, d’arrachement ou d’esquillement, une lecture fonctionnelle a été réalisée selon la méthodologie analytique développée par Semenov (1964). S’agissant d’objets de grandes dimensions, des répliques sur papier acétate ont été réalisées afin de permettre un examen au microscope. Deux registres d’activité en percussion lancée ont été déterminés, l’un orienté vers des travaux de boucherie, l’autre vers le travail du bois. Pour ce qui est des activités de boucherie, ces gros éclats massifs ont été utilisés comme des fendoirs, couperets ou feuilles de boucher. Sur les bords de ces instruments sont documentés de grands enlèvements résultant du choc sur les ossements durant la désarticulation ou le dépeçage des animaux. Les matières végétales dures, semi-dures et ligneuses ont quant à elles également été travaillées en percussion lancée, essentiellement dans l’objectif de les dégrossir. Certaines pièces de très grandes dimensions suggèrent une prise à deux mains et, dans ce cas, un seul fil de tranchant est utilisé. Sur les autres pièces, de moins grandes dimensions, pouvant être tenues avec une seule main, le nombre de parties actives est plus important (au moins deux). Ces parties actives sont souvent denticulées (plus ou moins grandes encoches retouchées ou non) au sein desquelles se concentrent les polis d’usage. Ces denticulations sont, dans certains cas, initialement aménagées, mais peuvent aussi résulter des chocs sur le matériau lors de la percussion. Ces deux registres d’activités seront donc ici présentés en détaillant et illustrant les stigmates et polis d’usage relatifs à chacun d’eux.Lire la suite

  • “Poor” archeological levels not to be forgotten: units of Middle and
           early Upper Magdalenian age in El Mirón Cave (Ramales de la Victoria,
           Cantabria, Spain)

    • Authors: aneveu
      Lawrence Guy STRAUS & Manuel R. GONZÁLEZ MORALES
      This succinct contribution focuses on description and preliminary interpretation of “minor” occupations of the large, strategically located El Mirón Cave on the edge of the Cantabrian Cordillera in eastern Cantabria (Spain) during the Middle and early Upper Magalenian that followed upon the massive, culturally rich, faunally dense, functionally complex deposits of the Initial and Lower Magdalenian. The ten levels analyzed here date to the Late Glacial, c. 15.5-12.5 uncal kya BP. At a time when the classic Middle Magdalenian of the nearby French Pyrenees developed and major residential sites with clear social links to it (via the key site of Isturitz) were occupied in the lowland coastal zone of Cantabria and Asturias (e.g. La Garma, Llonín, La Viña), El Mirón had reverted for the most part to the role of a short-term, special-purpose, perhaps logistical campsite, rather than as a long-term, large-scale hub residential base. It is tempting (and indeed traditional) to focus on levels with large numbers of lithic and osseous artifacts, as well as works of portable art and personal ornaments, which are so characteristic of the most famous Magdalenian occupations. However, in hunter-gatherer subsistence systems, the “minor” locations played a significant role in the human exploitation of territories (especially ones with such complex, high relief as Cantabrian Spain). The levels in question here include some that can be interpreted as hunting camps (suggested by high percentages of worked and unworked bladelets and some antler points within the small assemblages), partially reminiscent of the use to which the cave may have been put during pre-Initial Magdalenian times, notably during the Solutrean, which was relatively rich in stone points.Lire la suite

      Matías J. MANGO & Guillermo L. ALBANESI
      Conodonts from the upper La Silla (9.6 m thick) and San Juan formations (264.7 m thick) at the Cerro La Silla section are analyzed for the identification of faunal dynamics, biofacies and sea-level changes. The conodont collection of 11 388 specimens was recovered after digestion of 41 samples of carbonate rocks, totalizing 88.155 kg. Conodont total abundance and generic diversity graphs, as well as cluster analysis, reveal seven biofacies. The Colaptoconus, Tropodus-Reutterodus, Oepikodus-Prioniodus, Juanognathus-Bergstroemognathus, Juanognathus-Oepikodus-Protopanderodus, Juanognathus-Protopanderodus, Juanognathus-Semiacontiodus biofacies are determined. These biofacies represent middle to outer carbonate ramp environments for the San Juan Formation. The associated analysis of biofacies and lithology allow for the recognition of two transgressive events in the San Juan Formation at the Cerro La Silla section, which could be related to transgressive systems tracts (TST) that occurred during the Early and Middle Ordovician (middle Tremadocian-early Dapingian).Lire la suite

  • Macrofloral and microfloral changes in the Middle Jurassic plant

      The flora of the Cianowice 2 borehole (c. 20 km NW of Cracow, Poland), dominated by cycadophytes (mainly bennettitaleans) and conifers, shows high taxonomic diversity relative to the low number of specimens. Twenty species were identified in the 96 determinable plant fragments found in 27 core samples: Cladophlebis sp. (ferns), Pachypteris rhomboidalis (Ettingshausen) Nathorst and Ptilozamites cycadea (Berger) Möller (seed ferns), Anomozamites nilssonii (Phillips) Seward, Nilssoniopteris solitaria (Phillips) Cleal & Rees, Otozamites mimetes Harris, Otozamites parallelus Phillips, Pterophyllum thomasii Harris, Pterophyllum cf. aequale (Brongniart) Nathorst, Ptilophyllum cf. okribense forma ratchiana Doludenko & Svanidze, Ptilophyllum pecten Phillips, Ptilophyllum sirkennethii Watson & Sincock, Cycadolepis sp. (bennettitaleans), Pseudotorellia grojecensis Reymanówna, Pseudotorellia samylinae Nosova & Kiritchkova, Pseudotorellia sp. (Gymnospermae incertae sedis), Bilsdalea dura Harris, Mirovia szaferi Reymanówna, and Brachyphyllum stemonium Kendall (conifers). The floristic composition is supplemented by palynological data. The taxa were connected to five depositional successions distinguished along the core: one, alluvial fans; two, four and five, meandering/anastomosing river depositional systems with fluvial plain deposits; and three, lacustrine/backswamp environment developed on fluvial plain. The composition of the fossil plant assemblage changes with the depositional setting within the same range of taxa, seen mainly in changed combinations of taxa, which are most diverse in the fluvial plain deposits. Some taxa occur in a single depositional succession; some are present in two or three. The sporomorph assemblages of particular depositional environments differ significantly from the composition of the co-occurring macroflora: ferns occur sporadically in the macroflora of each depositional environment but they strongly dominate the sporomorph assemblage. Our proposed reconstruction of the palaeoenvironment is a slight rise descending into a valley with a depositionary basin, with gymnosperms on the slope and ferns at the base. Some species are shared between Cianowice and nearby Middle Jurassic localities in Grojec and Zabierzów, and the majority of taxa are known from the Middle Jurassic, suggesting that the Cianowice deposits are of that age.Lire la suite

      The Carrizal Formation, exposed in the Marayes-El Carrizal Basin (western Argentina), has been the focus of palaeobotanical studies since the late 1800s. The recent finding of well-preserved palyno­logical assemblages provides the first detailed studies about its palynofloras. In this paper, the 63 taxa identified in the unit are illustrated and discussed, as well as their stratigraphic distribution in equivalent palynological assemblages of Argentina. Some spore species are revised: Uvaesporites hammenii (Herbst) Césari, comb. nov., Retusotriletes wielandii (Jain) Césari, comb. nov. and Lundbladispora stellae (Herbst) Césari, comb. nov.

  • Iberoccitanemys atlanticum (Lapparent de Broin & Murelaga, 1996) n.
           comb.: new data on the diversity and paleobiogeographic distributions of
           the Campanian-Maastrichtian bothremydid turtles of Europe

    • Authors: aneveu
      Adán PÉREZ-GARCÍA, Francisco ORTEGA & Xabier MURELAGA
      Bothremydidae is the most abundant clade of turtles in the Campanian and Maastrichtian (Upper Cretaceous) fossil record of southwestern Europe. Several members of Foxemydina Gaffney, Tong & Meylan, 2006 are known in an area that includes Southern France and the North-Eastern half of Spain. The problematic ‘Polysternon’ atlanticum is the worst characterized, lacking a diagnosis that allows its specific validity to be confirmed, and whose generic attribution has been recognized as doubtful. Its presence was exclusively proposed in its type locality, the upper Campanian quarry of Laño, in Treviño County (Burgos Province, North of Spain). Despite the fact that knowledge about Bothremydidae has markedly increased after the description of ‘Polysternon’ atlanticum Lapparent de Broin & Murelaga, 1996, no new information about this species has been published since the 1990s. The analysis of abundant unpublished material of the bothremydid from Laño allows us to confirm the validity of this species. As a consequence of this study, it is not only identified in its type locality, but also in other Spanish regions and in the south of France. The diversity of Bothremydidae Baur, 1891 in the Upper Cretaceous of Europe is lower than previously considered. Thus, the species ‘Iberoccitanemys convenarum’ (Laurent, Tong & Claude, 2002), originally defined for the French record, and subsequently also identified in Spain, is identified here as a synonym of the species described in Laño. An emended diagnosis for the upper Campanian to upper Maastrichtian, Iberoccitanemys atlanticum (Lapparent de Broin & Murelaga, 1996) n. comb., is proposed.Lire la suite

  • Exceptionally preserved calcified sponge assemblages in Upper Jurassic
           carbonates of the eastern Getic Carbonate Platform (Southern Carpathians,

    • Authors: aneveu

      A rich poriferan assemblage was identified within the easternmost part of the Getic Carbonate Platform of Romania (Grădiștei Gorges). The excellent preservation state of most poriferans here led to the discovery of a new species (Neuropora gigantea Pleș & Schlagintweit, n. sp.) and to the identification of previously unknown diagnostic features in some species (Sarsteinia babai Schlagintweit & Gawlick, 2006 emend., Neuropora lusitanica Termier, 1985, Sphaeractinia steinmanni Canavari, 1893). Calciagglutispongia yabei Reitner, 1992, Sarsteinia babai and Sphaeractinia steinmanni are reported for the first time from the Upper Jurassic carbonates of the Getic Carbonate Platform. The sedimentary input fluctuations and the nutrient competition had an important role in understanding the morphological adaptations of the analysed species. The existing palaeoecological and palaeoenvironmental conditions generated different distribution patterns towards the reef profile and also preferential adaptations to a specific Tethyan domain. As opposed to the poriferan assemblages from the northern Tethyan shelves, these organisms formed sponge-coral-microencruster boundstones at the margins and fore-reefal zones of isolated carbonate platforms within the intra-Tethyan realm. The importance of calcified sponges in reef-zonation is highlighted by the establishment of a general zonation model. Three zones can be distinguished: 1) Cladocoropsis-Milleporidium zone (back-reef area); 2) Bauneia-Chaetetopsis-Parastromatopora zone (central reef area); and 3) Sphaeractinia/Ellipsactinia-Neuropora zone for the fore-reef area. In the absence of a true reef framework these calcified sponges developed typical morphologies, environmental adaptations and partnerships with other biotic groups which strongly influenced the carbonate production throughout the intra-Tethyan domain.Lire la suite

  • Bird remains from the Middle Paleolithic levels (MIS3) of Llonin Cave

      Birds are abundant in fossil assemblages of Quaternary sites; they can be used in landscape recon­struction as they are well adapted to the environment. Here we present the analysis of the avian assemblage from the Middle Paleolithic levels of the Llonin Cave, where 558 bird remains have been recovered from levels G-VI and CP-VIII, belonging to at least ten different taxa: Aves indet., Galliformes indet., Lagopus lagopus Linnaeus, 1758, Tetrastes bonasia Linnaeus, 1758, Columba livia/oenas Gmelin, 1789/Linnaeus, 1758, Passeriformes indet., Alaudidae indet., Motacilla sp., Turdus sp., Corvidae indet., Garrulus glandarius Linnaeus, 1758, Pyrrhocorax sp., Pyrrhocorax pyrrhocorax Linnaeus, 1758, Pyrrhocorax graculus Linnaeus, 1766 and Corvus corax Linnaeus, 1758. This assemblage is similar to other assemblages from the Upper Pleistocene of the north of the Iberian Peninsula, and it reflects a mixed landscape, with open areas and woodland. The taphonomic analysis points to a mixed origin of the accumulation, mainly formed by medium-sized corvids dying in the cave, and also raptors accumulating their prey.Lire la suite

  • Ancestral foxes at the gates of Europe: the Pliocene fox from Çalta-1
           (Turkey) and their relationships with Asian and European Plio-Pleistocene

    • Authors: aneveu
      The Pliocene record of genus Vulpes Frisch, 1775 in Eurasia is scarce, coming from few sparse localities. The lack of a comprehensive and integrated revision led to the description of numerous different taxa, often only tentatively related to extant species but not with one another. Çalta-1 is an important Pliocene site located in the Anatolian region of Turkey, dated to 4.0 Ma. In the present review, we reappraise the interesting record of Vulpes galatica Ginsburg, 1998. Morphological and morphometric evidence suggests a strong similarity between this taxon and the early Late Pliocene V. beihaiensis Qiu & Tedford, 1990, recovered from the Chinese Yushe Basin. Such evidence favors the parsimonious interpretation of synonymy between the two species, under the name V. beihaiensis. This hypothesis opens a new interpretation on the biogeography of the Pliocene-Early Pleistocene foxes of Eurasia. Vulpes beihaiensis links the Asian and European records, with its affinity to V. ­alopecoides (Del Campana, 1913) and, eventually, to the extant red fox (Vulpes vulpes (Linnaeus, 1758)).Lire la suite

  • Prolagus Pomel, 1853 (Lagomorpha, Mammalia) in the framework of the
           Pliocene faunal rearrangements in central Europe

    • Authors: fsissi
      Stanislav ČERMÁK, Chiara ANGELONE & Blanca MONCUNILL-SOLÉ
      Pliocene occurrences of Prolagus Pomel, 1853 in central Europe represent anomalies out of the peri-Mediterranean area, at that time the core distribution of the genus. Though known for several decades, those materials never underwent a general revision. The detailed analysis and comparison of all available materials performed here revealed two phenotypic entities: 1) Prolagus bilobus Heller, 1936 (Gundersheim localities, Raciszyn 1), for which were defined additional diagnostic characters and ontogenetic patterns of variation (d3/p3 and mandible); and 2) Prolagus sp. (Beremend 26/39), probably a new species. All the available occurrences are dated to MN15b. The morphological trends towards the reduction of p3 entoconid and of enamel folding evidenced in Pliocene Prolagus of western Europe cannot be recognized in coeval central European forms. Evidently, P. bilobus and Prolagus sp. do not pertain to the western European clade, whose separation is known since the early late Miocene. We hypothesize that at least P. bilobus originated from a dispersal of Prolagus from south-eastern regions of Europe rather than from an autochthonous speciation of isolated populations left as a relict after the southward displacement of Prolagus distribution area. The dispersal is likely to be related to the Pliocene global environmental changes during which extensive faunal rearrangements took place in Europe, in particular to those near the early/late Pliocene boundary.Lire la suite

  • Tetraodontiformes (Osteichthyes, Actinopterygii) from the Miocene of
           Argentina: with the southernmost record of fossil Tetraodontidae

    • Authors: aneveu
      Soledad GOUIRIC-CAVALLI, Maria de las Mercedes AZPELICUETA & Alberto L. CIONE
      Teleostean evolution produced enormous variation in tooth morphology. This variation is related to the exploration and exploitation of very diverse dietary niches. Among extant fishes, several taxa of the order Tetraodontiformes (e.g. pufferfishes, porcupinefishes and ocean sunfishes) have evolved highly specialized beak-like tooth structures. Here we provide the first description of tetraodontiform crushing beaks from Argentina. A single complete premaxillary beak recovered from the early Miocene Gaiman Formation in Chubut Province is assigned to Molidae based on its premaxillaries being completely fused to one another along the midline, general morphology, and size. Moreover, due to the putative presence of rows of teeth fused to the thick and massive bone structure, the specimen might belong to the genus Ranzania Nardo, 1840. Several premaxillary beaks recovered in the late Miocene Paraná Formation of Entre Ríos Province are assigned to Tetraodontidae Bonaparte, 1832 based on the presence of long, slender, rod-like, and parallel dental units; premaxillae not fused in the midline but articulated by interlocking emarginations, and a few small and one large trituration dental units. Argentinian tetraodontiform fishes inhabited the warm-temperate Paranense and Patagoniense Seas (marine transgressions developed in southeastern South America) during the early-late Miocene; these specimens are the southernmost fossil record of the group worldwide. Tetraodontiforms are extremely rare in recent Argentinian marine waters. The new fossil records agree with the higher sea water surface temperatures suggested both locally and worldwide for the Miocene.Lire la suite

  • The Early Pleistocene ectothermic vertebrates of Pietrafitta (Italy) and
           the last Western European occurrence of Latonia Meyer, 1843

    • Authors: aneveu
      Leonardo SORBELLI, Andrea VILLA, Sergio GENTILI, Marco CHERIN, Giorgio CARNEVALE, Emanuel TSCHOPP & Massimo DELFINO
      The Early Pleistocene site of Pietrafitta (central Italy) produced a rich vertebrate assemblage from the Late Villafranchian Land Mammal Age (late MN18). Geological and paleobotanical data from Pietrafitta indicate a lacustrine environment, surrounded by a humid deciduous broadleaved forest with a temperate climate. The vertebrate assemblage consists of at least 40 taxa including actinopterygians, amphibians, reptiles, birds, and mammals. Here, we concentrate on the ichthyofaunal and herpetofaunal remains. The ichthyofauna includes Barbus Cuvier and Cloquet, 1816, Scardinius Bonaparte, 1837, aff. Squalius Cuvier, 1817, and Tinca Cuvier, 1817. The two anuran genera are the large-sized alytid frog Latonia Meyer, 1843 and the “green frog” Pelophylax Fitzinger, 1843. Three snake precloacal vertebrae were recognized, one attributed to Colubrines indet., another one to ­Natrix sp. Laurenti, 1768, and the largest and most complete vertebra is referred to the genus Vipera s.l. Laurenti, 1768 (cf. gr. “Oriental vipers”). The chelonian fossils, including some complete carapaces and plastrals, are attributed to the European pond turtle (Emys gr. Orbicularis Linnaeus, 1758) and Hermann’s tortoise (Testudo hermanni Gmelin, 1789).Lire la suite

  • Variability of the lower incisors in the cave bears (Carnivora, Ursidae)
           from the Caucasus and Urals

    • Authors: aneveu
      Morphometric and morphotypic variability of the cave bear lower incisors from two different geographic regions (Caucasus and Urals), different stratigraphic periods (Middle and Late Pleistocene), and bearing different mitochondrial haplogroups (kudarensis (Baryshnikov, 1985) and ingressus Rabeder, Hofreiter & Withalm, 2004) was studied. Urals Ursus kanivetz Vereshchagin, 1973 is clearly distinguished from Caucasian U. kudarensis by morphology of the upper and lower incisors. The Urals cave bear exhibits more derived features compared to the Caucasian cave bears. Ursus kanivetz exhibits the largest average size of the lower incisors. The lower incisors of U. kanivetz are clearly distinct from those in U. kudarensis. Also, U. kudarensis specimens display a clear separation from all other groups of cave bears. Morphology of the incisors of the cave bears is clearly different from that of Early Pleistocene U. etruscus G. Cuvier, 1823, as well as from that of recent U. arctos L., 1758 (Rabeder, 1999) and U. maritimus Phipps, 1774. Our results suggest that the incisors of the cave bears are similar to each other and demonstrate a hypocarnivorous adaptation as a major evolution trend in the lineage of Spelearctos group. These adaptation features were perhaps developed in parallel in different lineages of the cave bears (U. spelaeus Rosenmüller, 1794 and U. kanivetz on the one hand and U. kudarensis on the other hand) in the Late Pleistocene.Lire la suite

  • Siega Verde and the open-air rock art of the northern Iberian Peninsula

    • Authors: fsissi
      Siega Verde was the third open-air rock art site to be discovered in the Iberian Peninsula, even before Côa and the controversy that followed that discovery. Its practicable size and the study carried out without any publicity allowed the analysis of a new reality that would change the interpretation of Palaeolithic art. From the start of the research, stylistic criteria were used to date the art in the absence of archaeological excavations. Although this has often been criticized, it meant that Siega Verde and Côa could be dated from Leroi-Gourhan’s Style II onwards. Excavations at Fariseu, a site belonging to Côa in Portugal, have proved that hypothesis archaeologically, as well as supporting the applicability of Leroi-Gourhan’s styles. Siega Verde is a good representative of Palaeolithic art in the open, on rocks by a river-bank or on prominent hills, but it is not the only form that can be catalogued as open-air rock art, because there are intermediate forms. These are found in cave entrances and in rock-shelters all over the Iberian Peninsula, especially in areas where little evidence of Palaeolithic art used to be known, such as on the southern Mediterranean coast and in Andalusia. This site possesses an exterior Upper Palaeolithic art ensemble, similar to the art found inside caves and of the same age, but in a different location. Formal relationships are usual inside and outside the caves and in both cases they represent a communicative code that did not need the dark and mystery to be expressed.Lire la suite

  • The anatomy, phylogenetic relationships, and autecology of the carnivorous
           lizard “Saniwa” feisti Stritzke, 1983 from the Eocene of Messel,

    • Authors: aneveu

      The evolution and interrelationships of carnivorous squamates (mosasaurs, snakes, monitor lizards, Gila Monsters) are a contentious part of reptile systematics and go to the heart of conflict between morphological and molecular data in inferring evolutionary history. One of the best-preserved fossils in this motley grouping is “Saniwa” feisti Stritzke, 1983, represented by complete skeletons from the early-middle Eocene of Messel, Germany. We re-describe it on the basis of superficial examination, stereoradiography, and high-resolution X-ray computed tomography of new and published specimens. The scalation of the lizard is unique, consisting of small, keeled scales on the head (including a row of enlarged medial supraorbitals) and large, rhomboidal, keeled scales (invested by osteoderms) that covered the rest of the body. Two paired longitudinal rows of enlarged scales ran down the neck. The head was laterally compressed and box-shaped due to the presence of a strong canthal-temporal ridge; the limbs and tail were very long. Notable osteological features include: a toothed, strap-like vomer; septomaxilla with a long posterior process; palpebral with a long posterolateral process; a lacrimal boss and a single lacrimal foramen; a well-developed cultriform process of the parabasisphenoid; two hypoglossal (XII) foramina in addition to the vagus; a lack of resorption pits for replacement teeth; and possibly the presence of more than one wave of developing replacement teeth per locus. There are no osteological modifications suggestive of an intramandibular hinge, but postmortem displacement of the angular-prearticular-surangular complex in multiple specimens suggests that there might have been some degree of mobility in the lower jaw based on soft-tissue modifications. Using phylogenetic analyses on a data-set comprising 473 morphological characters and 46 DNA loci, we infer that a monophyletic Palaeovaranidae Georgalis, 2017, including Eosaniwa Haubold, 1977, lies on the stem of Varanidae Merrem, 1820, basal to various Cretaceous Mongolian taxa. We transfer feisti to the new genus Paranecrosaurus n. gen. Analysis of gut contents reveals only the second known specimen of the cryptozoic lizard Cryptolacerta hassiaca Müller, Hipsley, Head, Kardjilov, Hilger, Wuttke & Reisz, 2011, confirming a diet that was at least partly carnivorous; the preservation of the teeth of C. hassiaca suggests that the gastric physiology of Paranecrosaurus feisti (Stritzke, 1983) n. comb. had high acidity but low enzyme activity. Based on the foregoing and linear discriminant function analysis, we reconstruct P. feisti n. comb., as a powerful, widely roaming, faunivorous-carnivorous stem monitor lizard with a sensitive snout. If the molecular phylogeny of anguimorphs is correct, then many of the features shared by Helodermatidae Gray, 1837 and Varanidae must have arisen convergently, partly associated with diet. In that case, a reconciliation of morphological and molecular data would require the discovery of equally primitive fossils on the helodermatid stem.Lire la suite

  • Dispersal and early evolution of the first modern cricetid rodents in
           Western Europe: new data from the Vallès-Penedès Basin (Catalonia)

    • Authors: fsissi
      Modern cricetids originated in Asia and dispersed into Western Europe by the end of the early Miocene, where they quickly became major components of the rodent faunas. Here we review the early Miocene rodent record of the genera Democricetodon Fahlbusch, 1964 and Megacricetodon Fahlbusch, 1964 in the Vallès-Penedès Basin (Catalonia, Spain). Democricetodon is represented by four species in the studied sites (D. hispanicus Freudenthal, 1967, D. cf. decipiens (Freudenthal & Daams, 1988), D. gracilis Fahlbusch, 1964 and a large-sized undetermined species) and Megacricetodon by one (M. primitivus (Freudenthal, 1963)). The cricetid succession bears several similarities with that of the nearby Calatayud-Montalbán Basin (East-Central Spain) to the point that the same detailed local biostratigraphy could be extended to the Catalan basin. The rare presence of certain Democricetodon species (D. gracilis) and other small mammal taxa also reveal affinities with regions beyond the Iberian Peninsula and indicate that the Vallès-Penedès Basin was more humid and forested than inland Iberian basins during the early Miocene.Lire la suite

Parmi les très nombreux objets entrant dans cette catégorie, nous ne ­présenterons ici que les pièces montrant des traces d’utilisation en percussion. Bien que ces traces soient généralement présentes sur des galets, nous verrons que d’autres types de matériaux ont été utilisés, avec notamment le réemploi de silex initialement taillés pour d’autres usages. L’étude concerne trois sites aurignaciens (les abris Blanchard et Castanet à Sergeac et l’abri Cellier à Tursac) et les niveaux du Gravettien final de deux autres sites (les abris Pataud et de Laugerie-Haute aux Eyzies-de-Tayac). Les collections étudiées ont des origines très diverses : collections issues de fouilles anciennes, collecte dans les déblais de fouilles anciennes et fouilles actuelles.

           (Squamata, Mosasauridae, Mosasaurinae) from the Upper Cretaceous of the
           vicinity of Jerusalem – Biostratigraphical insights from microfossils

    • Authors: fsissi
      Nathalie BARDET, Delphine DESMARES, Raquel SÁNCHEZ-PELLICER & Silvia GARDIN
      Briefly mentioned in 1915 by the palaeontologist Répelin, the mosasaurid Liodon asiaticum Répelin, 1915 was found by a missionary to Africa, a Father Ruffier, in Late Cretaceous strata near Jerusalem (without further details on the exact provenance). This material was never described in detail, figured, or revised and was recently rediscovered in the collections of the Muséum d’histoire naturelle of Marseille (Provence, southern France). Here we describe and figure for the first time this material, which now includes more specimens than the original lot mentioned by Répelin, and we propose new systematic assignments for the identified specimens. First of all we demonstrate that the five original vertebrae briefly described by Répelin representing a composite assemblage and being are not diagnostic at the specific level,. Thus Liodon asiaticum should be considered a nomem dubium. The most complete and diagnostic specimen belongs to a Mosasaurini (Mosasaurinae) incertae sedis, close to Mosasaurus Conybeare, 1822 and Plotosaurus Camp, 1951, as shown by in the unique configuration of its frontal-parietal-postorbitofrontal complex. The two other specimens are referred to identified as indeterminate Mosasaurinae. The study of several groups of microfossils (calcareous nannofossils, planktonic foraminifera and palynomorphs) found in the white chalk preserved with most of the bones constrains the age of these mosasaurid remains to the lower part of the middle Campanian (C. plummerae (Gandolfi, 1955) / G. rosetta (Carsey, 1926) and CC18 / UC14-15a Zones). This corresponds to the local Mishash Formation that crops out extensively East of Jerusalem (Mount of Olives and surroundings). Father Ruffier probably collected these bones in one of the outcrops of this formation, possibly not very far from where he worked and lived (Saint-Anne Community in Jerusalem). These chalky levels, common in the Middle East, represent a shallow and rather open marine environment, possibly near-shore.Lire la suite

  • A chrono-cultural reassessment of levels III-V from El Cuco rock-shelter:
           a new sequence for the late Middle Palaeolithic – early Upper
           Palaeolithic boundary in the Cantabrian region (northern Iberia)

    • Authors: aneveu
      The Iberian Peninsula is one of the key areas for studying the last populations of Neanderthals and the arrival in Europe of the first anatomically modern humans. In the Cantabrian region, this process can be traced in just a few sites with levels dating to the final stages of the Middle Palaeolithic and the earliest phases of the Upper Palaeolithic. One of these singular enclaves is El Cuco rock-shelter, where the sequence was initially dated by 14C only to the early Upper Palaeolithic sensu lato. However, new studies and datings now place this archaeological sequence in the late Mousterian and the Aurignacian. In this article we present a chrono-cultural reassessment of the upper levels of El Cuco (III-V), including a study of the large mammals. Levels Vc and Vb (>43.5-40.5 ky uncal BP) date from the late Mousterian, whereas levels Va, IV and III (c. 36.5-30 ky uncal BP) cover an interval extending at least from the Early Aurignacian to the Evolved Aurignacian. Particularly noteworthy is the discovery in level Va of a set of decorative beads made from marine shells in a context of possible symbolic behaviour.Lire la suite

  • A new species of dog from the Early Pleistocene site of Venta Micena
           (Orce, Baza Basin, Spain)

    • Authors: fsissi
      The site of Venta Micena (Orce, Spain), c. 1.6 Ma, preserves one the best paleontological records of the early Pleistocene large mammals fauna in Europe. Here we describe the specimens of the genus Canis Linnaeus, 1758 in the context of the late Villafranchian and Epivillafranchian fossil dogs from Eurasia. Anatomical and metric data suggest that the Venta Micena Canis form differs from the classical records of Canis etruscus Forsyth Major, 1877 and Canis arnensis Del Campana, 1913, and that it forms part of the younger Canis mosbachensis Soergel (1925) lineage, also recorded in two slightly younger sites of the Orce site complex, Barranco León and Fuente Nueva-3, dated to c. 1.4 Ma. The anatomy of the Venta Micena fossil material shows features that resemble the Canis forms from the Caucasian site of Dmanisi, dated to 1.8 Ma, and Canis ex gr. C. mosbachensis. Nevertheless, dental peculiarities support the creation of a new chrono-species, Canis orcensis n. sp., from the town of Orce. Morphological and paleoecological data suggest that this species probably consumed more vertebrate flesh than other similar sized early Pleistocene canids (i.e., a trend to hypercarnivory), which had more omnivorous dietary habits.Lire la suite

  • A road to nowhere' The non-transitional sequence at El Esquilleu
           (Cantabria, Spain)

    • Authors: fsissi
      El Esquilleu cave has one of the most complete Middle Paleolithic stratigraphies of northern Iberia with a complete chronological framework almost continuous from the beginning of MIS3. The complete analysis of the materials including the last section of the sequence corresponding to the last chronological interval of the occupation in the region shows clear evolutionary tendencies by important changes in the composition of the lithic assemblage. Its study confirms a continuous occupation without any gaps during the Mousterian until recent dates but without any Upper Paleolithic presence. This sequence, referenced to the Mousterian settlement of the Picos de Europa mountains, testifies to the existence of a Mousterian presence in northern Iberia with no clear relation to other Cantabrian areas. Consequently, its occupation without a break until the crucial phase of the end of the Middle Paleolithic suggests a non-transitional process in the history of local Neanderthal groups.Lire la suite

  • Late Paleogene herpetofaunas from the crossroads between two continents
           – new amphibian and reptile remains from the Oligocene of southern
           Balkans and Anatolia

    • Authors: aneveu
      Georgios L. GEORGALIS, Andrej ČERŇANSKÝ & Serdar MAYDA
      We describe here new amphibian and reptile remains from three Oligocene localities of Turkey. Two of the localities (Kavakdere and Kocayarma) are situated in southeastern Europe and the other one (Kargi 2) in Anatolia, both areas where Oligocene herpetofauna is practically almost unknown. The material consists of albanerpetontids, pelobatid anurans, turtles, crocodylians, lacertids, scinciformatans, anguines, and “tropidophiids”. Albanerpetontids are for the first time identified in southeastern Europe, with the material being reminiscent of the younger species Albanerpeton inexpectatum Estes & Hoffstetter, 1976; the material potentially represents the oldest record of that species. Pelobatids, scinciformatans, and “tropidophiids” represent the oldest occurrences of these clades in the northeastern Mediterranean. The anguine genus Ophisaurus Daudin, 1803 is identified for the first time in the Paleogene of Eastern Europe. The “tropidophiids” are referred to two genera, Falseryx Szyndlar & Rage, 2003 and tentatively also to Platyspondylia Rage, 1974, with the latter having been so far exclusively known from western and central Europe. The role of a potential southern dispersal route of taxa among Asia and Europe, involving the area of southern Balkans and Anatolia, similarly to what has been recently demonstrated for mammals, is highlighted also for amphibians and reptiles.Lire la suite

  • The Mousterian loess sequence La Combette (France) and its chronological
           framework: A re-investigation

    • Authors: aneveu

      The La Combette rock-shelter, located in the Luberon mountains (Southern France), is an essential local archaeological discovery. The site comprises several Palaeolithic layers suggesting multiple phases of Mousterian occupation. The sediment sequence of c. 7 m thickness indicates rapid changes in the environmental conditions, which led to an abandonment of the site. While the first chronological studies were carried out in the late 1990s, in 2014, new sediment samples were taken for state-of-the-art luminescence-dating analyses using fine grain (4-11 µm) quartz and polymineral separates. Samples were taken from the loess-dominated upper archaeological levels A to D (upper main unit) as well as from the anthropogenic layer E, embedded in a fluvial context, and from the bottom deposits of the layer F/G. Here we present the obtained chronological dataset in conjunction with 24 so far unpublished thermoluminescence dating results from burnt flint artefacts from layers E and F/G. We combine and discuss our results against previous chronological datasets, which seem to be broadly confirmed by our new findings framing the sedimentation history of La Combette at 78.3 ka to 39.4 ka. In summary, it appears that the local environmental conditions were deeply impacted by the climatic changes during MIS 4/3. This caused rapid sediment influx that finally rendered the rock shelter uninhabitable as a potential refuge, until its re-discovery in the second half of the 20th century.Lire la suite

  • An enigmatic specialized new eutherian mammal from the Late Cretaceous of
           Western Europe (Northern Pyrenees)

    • Authors: aneveu
      Emmanuel GHEERBRANT & Dominique TEODORI
      We report the discovery of a new Late Cretaceous eutherian mammal, Azilestes ragei n. gen., n. sp. from the Mas-d’Azil northern Pyrenean site (France), which is among the largest known. It is only known from a broken lower jaw found in uppermost levels of the Grès de Labarre Formation (early Maastrichtian). Despite its poor preservation, it displays distinctive specialized features with respect to known Cretaceous eutherians. This includes a reduced premolar formula and shortened and robust jaw, an incipient hypolophid, and a cingular-like postcristid and hypoconulid. The phylogenetic analysis suggests indeed a possible stem relationship between Azilestes n. gen. and some clades of herbivorous Cenozoic placentals, but with weak support. Several molar features reminiscent of the Zhelestidae, especially Valentinella Tabuce, Vianey-Liaud & Garcia, 2004, support instead that Azilestes n. gen. is a basal eutherian showing early specialization in a herbivorous diet convergent with some crown placentals. Whatever the suprageneric position of Azilestes n. gen., which remains to be clarified with additional material, its discovery highlights a significant diversity of European Cretaceous eutherians in contrast to their very poor fossil record.Lire la suite

           from the predeubeli/deubeli Biozone (upper Homerian, Wenlock, Silurian),
           the recovery phase after the lundgreni Extinction Event

    • Authors: fsissi
      Anna KOZŁOWSKA & Denis BATES
      Papiliograptus retimarginatus n. sp. is reported from the praedeubeli/deubeli Biozone, upper Homerian (Silurian) of the Bartoszyce IG-1 drill core of Poland, Baltica. It is the second species of the genus Papiliograptus Lenz & Kozłowska-Dawidziuk, 2002, belonging to the new retiolitid fauna of the recovery period after the lundgreni Extinction Event. Two characteristic features of the new retiolitid fauna are the development of a geniculum and singular or paired genicular structures. The new form has extremely wide, singular, reticulated genicular processes. It is suggested that these structures may have been an adaptation to prevent the planktonic colony from sinking in the water column.Lire la suite

  • Diversité des outils et des activités de percussion à la fin du MIS 9
           dans le niveau 6 d’Orgnac 3 (Ardèche, France)

    • Authors: aneveu
      Cyrielle MATHIAS, Cyril VIALLET & Anne-Marie MOIGNE
      Le niveau 6 d’Orgnac 3 correspond à une occupation humaine en grotte, datée de la fin du MIS 9. Il a livré un riche assemblage lithique et paléontologique, témoin d’activités diversifiées des Homininés. Cet article propose un focus sur les différentes activités de percussion lancée, identifiées d’après le matériel lithique et osseux, à la suite d’une analyse technologique et tracéologique. Les activités de taille de la pierre sont les plus représentées, visibles au travers de percuteurs et retouchoirs (en os et en pierre). Des phénomènes de recyclage ont également été mis en évidence, avec des nucléus vraisemblablement utilisés comme percuteurs. Le bulbe d’un éclat présente des endommagements caractéristiques d’un emploi comme retouchoir (« éclat à bulbe piqueté »). Ces phénomènes sont fréquents au Paléolithique moyen et sont ici mis en évidence dès les premières phases de ces techno-complexes. Au sein des pièces façonnées, un « chopper » présente des macro-traces caractéristiques d’une activité menée en percussion lancée sur un matériau dur non minéral (os ?). Les restes d’herbivores ont été fracturés de manière anthropique pour récupérer la moelle, les fragments de diaphyses ayant été ponctuellement utilisés comme retouchoirs par la suite. Les activités de percussion occupent ainsi une place importante dans les modes de vies préhistoriques (taille de la pierre, acquisition et transformations de matériaux liés à la subsistance). La diversité de l’outillage de percussion pour un même registre d’activité témoigne d’une spécialisation technologique, tandis que le recyclage montre les capacités d’adaptation des Homininés à la fin du Pléistocène moyen face aux contraintes matérielles liées à leur environnement.Lire la suite

  • New skull material of Pleistocene dwarf deer from Crete (Greece)

    • Authors: aneveu
      Ann-Marie SCHILLING & Gertrud E. RÖSSNER
      In the Pleistocene faunas of the island of Crete, Cervidae was one of the most abundant taxa. Respective species vary in body size, including dwarfs, and skeletal morphology; however, the number of species and the identity of the mainland ancestor(s) are still debated. In this paper, we morphologically and morpho­metrically describe and analyze eight skulls of Cretan deer from a so far little known fossil site near Gerani, Rethymnon, Greece. The recorded character suite allows for affiliation to dwarfed Candiacervus Kuss, 1975, Candiacervus ropalophorus de Vos, 1984 and C. reumeri van der Geer, 2018. It comprises previously unknown unique traits, some of them hinting to sexual dimorphism. Comparisons of the Candiacervus skulls presented here with those of cervids belonging to Megalocerotini Brooke, 1828, s.s. and s.l. stress certain similarities; yet more material is needed to reconstruct Candiacervus’ phylo­genetic position. The newly detected craniodental specifics allow for more insights into island adaptation of Candiacervus; at the same time, they blur the morphological heritage of their mainland ancestors.Lire la suite

  • Taphonomy of a Panopea Ménard de la Groye, 1807 shell bed from the Pisco

      Invertebrate taphonomy can provide significant information about the post-mortem processes that affected the fossil record. In the East Pisco Basin of southern Peru, a Panopea Ménard de la Groye, 1807 shell bed was found in the upper Miocene strata of the Pisco Formation, hinting at a peculiar biostratinomic and diagenetic history. This bed contains abundant invertebrate fossil molds cemented by dolomite. The specimens of the deep infaunal bivalve, Panopea sp., occur together with bivalves representative of shallow infaunal species (Trachycardium sp. and Dosinia ponderosa [Gray, 1838]) and balanid barnacles, which are sessile encrusters. The Panopea specimens host compound molds evidencing an abundant encrusting fauna, including serpulids, ?foraminifera, bryozoans, and barnacles that colonized the inner surfaces of the valves before their final burial. We hypothesize that short-term, storm-related processes exhumed the living bivalves, resulting in a sedimentological concentration of relatively well-preserved shells. After the death of the exhumed bivalves, the inner surfaces of the articulated Panopea shells, representing hard-substratal, sheltered environments on an otherwise unstable sandy seafloor (i.e., “benthic islands”), were colonized by different encrusting organisms. Following the final burial, dolomite precipitated, cementing the sediment infill of the valves. Lastly, a decrease of pH occurred at the sulfate reduction-methanogenesis boundary, inducing the dissolution of the shell carbonate.Lire la suite

  • Stratigraphy, age, and vertebrate palaeontology of the latest Cretaceous
           Quintanilla la Ojada locality (Basque-Cantabrian Region, northern Spain):
           a synthesis

    • Authors: fsissi
      José-Carmelo CORRAL, Ana BERRETEAGA, Francisco José POYATO-ARIZA, Nathalie BARDET, Henri CAPPETTA, Marc FLOQUET, Humberto ASTIBIA, Ainara BADIOLA & Xabier PEREDA-SUBERBIOLA
      The Quintanilla la Ojada section (Basque-Cantabrian Region, northern Spain) has yielded two assemblages of Late Cretaceous vertebrates, deposited during the Maastrichtian in coastal environments and related to a transgressive lag at the base of the Valdenoceda Formation. Numerous teeth of Elasmobranchii and Actinopterygii are the most prevailing fossil material, although scarce teeth of marine reptiles (Mosasauridae) and dinosaurs (Hadrosauridae) also occur. The presence of one hadrosaurian tooth, a terrestrial taxon, constitutes the first report of ornithischians in the Valdenoceda Formation. The fossil vertebrate association of Quintanilla la Ojada is similar to that discovered in Albaina (Treviño County, Burgos), also located in the Basque-Cantabrian Region, although relatively younger in age. Both fossil sites are characterised by a mixture of taxa from the northern and southern margins of the Mediterranean Tethys (north-European and north-African outcrops).Lire la suite

  • Barremian anurans of the Iberian Peninsula: new insights into their
           taxonomic diversity

    • Authors: aneveu

      The Barremian continental successions of the Iberian Peninsula have yielded numerous remains of anurans. Some of these finds consist of fragmentary bones whereas others furnish more complete evidence on the skeletal morphology and proportions of the represented taxa. Notwithstanding the foregoing, most of these records have been ascribed either to the relatively basal extant costatan clade or to the poorly known extinct genus Eodiscoglossus Villalta, 1954 based on insufficient data. Recent revisions of some of these materials have demonstrated the presence of traits presumably plesiomorphic and unknown in extant costatans, thereby casting doubts on their phylogenetic placements. Herein two specimens from the upper Barremian Las Hoyas Konservat-lagerstätte are thoroughly described and compared, providing evidence of additional anuran taxa in this site. One of these specimens, initially reported as cf. Eodiscoglossus, is referred to Wealdenbatrachus Fey, 1988, a genus already described in the coeval fossil site of Uña. Another specimen consisting of a partial postcranial skeleton is documented by a latex-rubber cast and a photograph; it represents a new taxon whose phylogenetic position remains uncertain due to the incompleteness of the available evidence. Comments on a third specimen that might belong to another taxon are included, although its detailed description awaits its full preparation. The overview of the Barremian taxa currently recognized from Iberia reveals the co-occurrence of taxa of different sizes, body proportions, and lifestyles, suggesting some ecological partitioning in consonance with the heterogeneous habitats represented in the yielding fossil sites.Lire la suite

  • The stapes of Thrinaxodon Seeley, 1894 and Galesaurus Owen, 1859: a case
           of study for intraspecific variability in basal cynodonts

    • Authors: fsissi
      Leandro C. GAETANO & Fernando ABDALA
      We surveyed the stapedial anatomy of Thrinaxodon liorhinus Seeley, 1894 and Galesaurus planiceps Owen, 1859, two iconic Early Triassic basal cynodonts. The complete characterization of this bone and the analysis of its morphological variability along the ontogeny within each taxon were possible through the study of eleven elements of Thrinaxodon Seeley, 1894 and nine of Galesaurus Owen, 1859. Our results highlight notable qualitative and quantitative differences among specimens of the same species. Stapes growth model in Galesaurus shows a positive allometry on the lateromedial length and on the anteroposterior width, whereas in Thrinaxodon there is a negative allometry in the anteroposterior width but the lateromedial length is isometric. This study offers a counterintuitive result of inordinate high intraspecific morphological variation of the stapes of basal non-mammaliaform cynodonts.Lire la suite

  • Fossil record of a Characiform in the Monte Hermoso Formation (lower
           Pliocene), Buenos Aires, Argentina. Palaeobiogeographical implications

    • Authors: aneveu

      The fossil record of fishes from the Farola de Monte Hermoso locality (lower Pliocene) in the southern Buenos Aires province, Argentina, shows an unusual composition. The locality at the southern boundary of the Brazilian Ichthyogeographic Realm. However, its fossil record is composed of fossil fishes that are not necessarily related to Brazilian lineages, namely indeterminate siluriforms, trichomycterid catfishes, and percomorphaceans. The aim of the present contribution is to describe and report for the first time isolated specimens belonging to Characidae fishes. In the Pampean region the fossil record of characids is restricted to Oligosarcus Günther, 1864 sp. from the late-middle Pleistocene. The present finding fills a temporal gap between the Paleogene and Quaternary reports and indicates that Brazilian fish lineages were present in the area by early Pliocene times, and may constitute an indirect evidence of the evolution of the basins in the southern Pampean Area.Lire la suite

  • Paleoclimate estimates for the Paleogene-Neogene in southern South America
           using fossil leaves as proxies

      Bárbara VENTO, Gabriela G. PUEBLA, Diego PINZÓN & Mercedes PRÁMPARO
      It is widely recognized that fossil leaves are good proxies for paleoclimate estimates, and leaf physiognomy analysis is a traditional technique used to make climate estimates. There are only a few paleoclimate reconstructions for the southern part of South America based on this technique. Here we report climate parameters using fossil leaves from the Río Turbio (Eocene-Oligocene) and Río Guillermo (Oligocene-early Miocene?) formations in southern South America, Cuenca Austral, Argentina. We used univariate (leaf margin and leaf foliar area analysis) and multivariate methods (CLAMP, DiLP) on two datasets from South America, in the Southern Hemisphere. Lower and upper members of the Río Turbio Formation show a mixed paleoflora represented by paratropical as well as cool-temperate taxa such as Nothofagus, with a similar percentage of untoothed fossil leaves. Climate estimates indicate warm and humid conditions for both Río Turbio Formation members. The Río Guillermo Formation is represented by mostly cool-temperate elements, mainly Nothofagus, and most with toothed margins. The paleoclimate analysis indicates a decrease in temperature and precipitation when comparing the two studied formations. Today, temperate forests in southern Argentina have a plant composition and climate more similar to the estimates made for the Río Guillermo Formation.Lire la suite

  • The first representative of the trap-jaw ant genus Anochetus Mayr, 1861 in
           Neogene amber from Sumatra (Hymenoptera: Formicidae)

    • Authors: aneveu
      The ponerine ant Anochetus miosumatrensis Ngô-Muller, Garrouste & Nel, n. sp. is described from a fossil alate female preserved in amber of Sumatra which is reputedly of Miocene age. On the basis of the general morphology, the fossil could be attributed to the extant Sumatran species group risii Brown, 1978. By comparing with the living environment of the extant species, this ant probably lived in a warm humid forest where it was trapped in dipterocarpacean resin during nuptial flight. Until now, the known Cenozoic distribution of the genus Anochetus was restricted to the Neotropical region. Thus A. miosumatrensis Ngô-Muller, Garrouste & Nel, n. sp. brings the first record of the genus from Indomalaya biogeographic region.Lire la suite

  • Early human occupations in Northwest Iberia: the archaeological record of
           the Lower Miño basin during the second half of the Middle Pleistocene

    • Authors: fsissi
      Eduardo MÉNDEZ-QUINTAS, Manuel SANTONJA, Alfredo PÉREZ-GONZÁLEZ, Martina DEMURO, Lee J. ARNOLD & Mathieu DUVAL
      The Miño River is one of the main Atlantic basins of Iberia and preserves extensive Pleistocene deposits. However, there is presently limited information concerning the first human occupation history of this region. Existing research undertaken across the region has identified a significant number of Large Flake Acheulean (LFA) sites with African affinities. These sites are associated with former fluvial environments and are now preserved as a sequence of fluvial terraces along the Miño River, located between relative elevations of + 40 m and + 20 m, and dated to between Marine Isotope Stages (MIS) 9 and 6. The chronological range and observed technological patterns are similar to those recognised in other areas of South western Europe, particularly the central Iberian Peninsula and Aquitanian region (France) during the second half of the Middle Pleistocene.Lire la suite
