  • GOING DEEPER INTO MODERN AND FOSSIL CROCODILIAN TOOTH MICROANATOMY: WHAT
           CAN BE INFERRED OF PALAEOENVIRONMENT AND TAPHONOMY FROM HISTOCHEMICAL
           ANALYSES'

      Abstract: Teeth provide information about the evolutionary pathway of an organism, its biology and habitat. This is the case even of fossilized teeth, since they have perdurable biomineralized structures, as biological apatite. The material that has been selected for this study comprises teeth from modern crocodilian individuals and extinct Cretaceous crocodylomorphs from Lo Hueco site. Microanatomy, histochemistry and crystallographic nature of enamel, dentine and cementum have been characterized by Polarized Light Microscopy, SEM-EDS, Confocal Raman Spectroscopy and SR-µXRD. A focus has been made on dentine lamination. In the fossil sample short-period incremental lines show alternate presence of dentinal tubules that has not been described previously either in living or fossil archosaur. This could be related to influence of environmental circadian rhythms in the abundance, size and/or activity of cells depositing dentine in the day-night cycle. Regarding histochemical and crystallographic compositions, the major and mostly unique phase is HA, but in the case of fossil teeth, a secondary phase identified as hematite appears locally between discontinuities of the material. Incremental lines would not be related to variation in chemical composition and furthermore do not present different HA crystallographic nature (different directions of HA or different crystallite sizes) either. Only small intensity oscillations are observed in the fossil sample by SR-µXRD which are compatible with the alternating abundance of dentinal tubules. Crystallinity differences between modern and fossil material, as crystallite size and presence of CO32- groups could be explained by postdepositional processes.

  • FISH OTOLITHS AND FORAMINIFERA FROM THE BORSKÝ MIKULÁŠ SECTION
           (SLOVAKIA, MIDDLE MIOCENE, UPPER BADENIAN, VIENNA BASIN) AND THEIR
           PALEOENVIRONMENTAL SIGNIFICANCE

    • Authors: ROSTISLAV BRZOBOHATÝ, BARBARA ZAHRADNÍKOVÁ, NATÁLIA HUDÁČKOVÁ
      Abstract: Thirty-eight otolith-based species of fishes and 41 foraminifera species have been recorded in the Borský Mikuláš-Vinohrádky section in the upper Badenian deposits in the eastern part of the Vienna Basin, in West Slovakia. Two new species of otoliths are introduced here: Thorogobius antirostratus n. sp. and Gerres mlynskyi n. sp. Among the foraminifera Biasterigerina planorbis and Elphidium crispum associated with other elphidiids, Lobatula lobatula and Cibicides crassiseptatum prevail. Overall, the family of Gobiidae dominate in the assemblage of otoliths (>90 % of specimens). Meso- and epipelagial fishes or diversified gadids and sciaenids are missing. From the molluscs, the first record of Aturia sp. in the Borský Mikuláš section is observed. Otoliths and foraminifera document a normal marine environment of well-aerated shallow water with a depth of 30-50 metres, with muddy to sandy bottoms of marine meadows and plenty of light in the subtropical climatic conditions. Several fish genera (for example Gerres) give evidence for the nearness of reef structures. There are no species (excepting Lesueurigobius vicinalis) in common with the known Lower Serravallian otolith fauna from the Eastern Paratethys. Some species from the Borský Mikuláš-Vinohrádky section can also be found in the Mediterranean Langhian-Serravallian interval and are interpreted as a relic of the lower Badenian (Langhian) fish assemblages.

  • A RUPELIAN CORAL REEF FISH ASSEMBLAGE FROM THE VENETIAN SOUTHERN ALPS
           (BERICI HILLS, NE ITALY)

    • Authors: GIUSEPPE MARRAMA', LUCA GIUSBERTI, GIORGIO CARNEVALE
      Abstract: Here we describe a new bony fish assemblage collected from a fossiliferous outcrop located in Perarolo, Berici Hills, Venetian southern Alps. The fossiliferous deposits pertain to the Rupelian (lower Oligocene) Castelgomberto Calcarenite and are indicative of a tropical marine shallow water setting associated with coral reefs. The assemblage is characterized by diminutive putative cryptobenthic fishes, including a single goby (family Gobiidae) and several cardinalfishes of the subfamily Pseudmiinae (family Apogonidae. Furthermore, a new apogonine of the extinct tribe †Eoapogonini, a new butteflyfish (family Chaetodontidae), and an indeterminate viviparous brotula belonging to the ophidiiform family Dinematichthyidae, are also present, and likely represented part of the epibenthic community. Some of the taxa described herein are among the first occurrences for their respective lineages in the fossil record. The Perarolo taxa document the first Oligocene coral reef fish assemblage known to date. Four taxa are described as new: †Arconiapogon deangelii gen. et sp. n., †Chaetodon (Blumchaetodon) wattsi subgen. et sp. n., †Oligopseudamia iancurtisi gen. et sp. n., and †Oniketia akihitoi gen. et sp. n.

  • THE TUROLIAN HIPPARIONS FROM CIOBURCIU SITE (REPUBLIC OF MOLDOVA):
           SYSTEMATICS AND PALEODIET

    • Authors: BOGDAN G. RĂŢOI, BOGDAN S. HAIDUC, GINA M. SEMPREBON, PAUL ŢIBULEAC, RAYMOND L. BERNOR
      Abstract: The Cioburciu hipparions, Republic of Moldova, are included in a Turolian assemblage, approximately dated between 9 and 7 million years. We assess herein their taxonomic position, systematics, biogeography and paleodietary habits. We have undertaken standard equid measurements as well as accessing the Vera Eisenmann website for measurements and images and analysed craniodental and postcranial elements. This assemblage has been determined to be of a medium-sized hipparion with an elongated muzzle, well developed preorbital fossa that is dorsoventrally extensive and placed close to the orbit, lacking a caninus fossa and having a prominent and deep buccinator fossa. As such, this assemblage is referable to Cremohipparion moldavicum Gromova 1952 common to the Western Ukraine, Balkans, Romania, Republic of Georgia, Turkey and Iran. We have employed a combination of gross cheek tooth wear morphology utilizing the mesowear method and a microscopic analysis of occlusal enamel scars utilizing the light microscope microwear technique. These complementary paleodietary methods indicate that these hipparions engaged in a mixed feeding dietary behavior and that the Cioburciu sample of C. moldavicum likely alternated its diet between browsing and grazing seasonally and/or regionally. A hierarchical cluster analysis based on average scratch and pit numbers positions this taxon among extant mixed feeding ungulates. Large pitting and gouging assessed through the microwear technique indicates occasional consumption of relatively coarser foods than typical mixed feeders or grazers or grit-laden food just prior to death while mesowear indicates that this was not a lifetime habit.

  • DANIAN (SBZ2) LARGER FORAMINIFERA FROM THE BECIRMAN FORMATION
           (SOUTHEASTERN TURKEY) AS EVIDENCE OF ROTALIIDS DIVERSITY IN LOWER
           PALEOCENE SHALLOW-WATER ENVIRONMENTS

    • Authors: DERYA SINANOĞLU, ANDREA BENEDETTI, NAZIRE ÖZGEN-ERDEM
      Abstract: An important shallow marine deposit is described and illustrated with focus on the systematics and biostratigraphy of larger foraminifera from three stratigraphic sections of the Becirman Formation from the Batman and Siirt regions (Southeastern Turkey). A quite diverse association, mostly dominated by rotaliids (11 species belonging to 7 genera) and subordinate porcelaneous and agglutinated taxa, is documented as well. The fossil assemblage, including Elazigina dienii, Rotospirella conica, Praelockhartia cf. neoakbari, Cuvillierina cf. sireli associated with Mardinella daviesi and Idalina sinjarica, indicates the late Danian SBZ2. The abundance of rotaliids is linked, in this time frame, to the recovery of the shallow benthic communities after the K/Pg extinction including increase of surface water temperatures and oligotrophy. This was possibly due to the climatic warming recorded at the end of the Danian (Latest Danian Event), thus promoting a rapid adaptative radiation of rotaliids at genus rank.

  • THE MIDDLE SMITHIAN (EARLY TRIASSIC) AMMONOIDS OF GORNJI BRČELI
           (SOUTHERN MONTENEGRO)

    • Authors: MARTIN ĐAKOVIĆ , LEOPOLD KRYSTYN , MILAN SUDAR
      Abstract: A rich Early Triassic (Smithian) ammonoid fauna discovered near the village of Gornji Brčeli (southern Montenegro) is unique for the Early Triassic of the western Tethys. The Smithian there is represented by a series of several tens of meters thick brown-red to grey-green marls and clays with intercalated, mica-rich, thin dark grey sandstones, and subordinate occurence of redeposited oolitic limestone. The fossils have been collected as scree material over a few square meters but are considered as contemporaneous since no unnatural association (condensation) was detected. The ammonoid assemblage is represented by 15 species, belonging to the genera Aspenites, Cordillerites, Dieneroceras, Abrekites, Owenites, Pseudaspenites, Pseudosageceras, Truempyceras, Wyomingites, Hanielites, Galfettites, Parahedenstroemia, Lingyunites and Pseudoflemingites, and can, by the presence of Owenites zitteli Smith, be correlated with the late Middle Smithian Nyamalites angustecostatus beds of the southern Tethys, the upper Owenites koeneni beds of South China or the Owenites beds of North America. Taxonomic composition of the ammonoid assemblage shows great similiarity with those of Spiti (India), NW Guangxi (China) and Nevada (USA), but also some with those of Salt Range (Pakistan) and Timor. A markedly dominance of involute, oxycone and platycone morphologies distinguishes the Gornji Brčeli fauna from other contemporaneous faunas and points to specific palaeoecological environmental conditions. Previously, three new species were described from this locality and in the present paper one more is added (Parahedenstroemia' tatjanae). Two species hitherto considered as synonyms (Abrekites arthaberi and Owenites zitteli) are revised and treated as valid based on new material from Gornji Brčeli.

  • MARINE FISHES (CHONDRICHTHYES, HOLOCEPHALI, ACTINOPTERYGII) FROM THE UPPER
           CRETACEOUS (CAMPANIAN) RYBUSHKA FORMATION NEAR BELOE OZERO, SARATOV
           OBLAST, RUSSIA

    • Authors: JUN A. EBERSOLE, SERGEY V. SOLONIN, DAVID J. CICIMURRI, MAXIM S. ARKHANGELSKY, NIKOLAY V. MARTYNOVICH
      Abstract: A diverse fish paleofauna occurs in the upper Campanian portion of the Rybushka Formation exposed near Saratov city in the Saratov Oblast, Russia. Twenty taxa have been identified, including two holocephalans (Ischyodus bifurcatus and Amylodon karamysh), twelve elasmobranchs (Synechodus sp., Cederstroemia sp., Cretalamna cf. C. borealis, C. cf. C. sarcoportheta, Archaeolamna kopingensis, Eostriatolamia segedini, E. venusta, Pseudocorax laevis, Squalicorax kaupi, Squalicorax morphotype 1, Squalidae indet., and Squatirhina sp.), and six teleosts (Pachyrhizodus sp., Saurocephalus lanciformis, Paralbula casei, Enchodus cf. E. dirus, E. cf. E. gladiolus, and E. petrosus). Many of these taxa are new to the Campanian fish record of Russia, and the assemblage demonstrates that there is significant taxonomic overlap between the Rybushka Formation paleofauna and that of North America.

  • OSTRACODS FROM THE LATE TRIASSIC (NORIAN) OF YUKON, CANADA: NEW TAXONOMIC
           AND PALAEOBIOGEOGRAPHIC INSIGHTS

    • Authors: MARIE-BÉATRICE FOREL, NICOLO' DEL PIERO, SYLVAIN RIGAUD, ROSSANA MARTINI
      Abstract: The present work investigates the significance of Late Triassic ostracods from the Yukon Territory, Canada, and adds to the scientific knowledge of the taxonomy of these organisms during the Norian, which remain poorly documented and understood. Fifteen limestone samples representing distinct marine palaeoenvironments cropping out at Lime Peak, Stikinia terrane, provided 90 species, including 9 newly described: Alatobairdia' sohni n. sp., Bairdia aksala n. sp., B. taan n. sp., B. yukonensis n. sp., Cornutobairdia yukonella n. sp., Lobobairdia whitella n. sp., Mirabairdia canadia n. sp., Hungarella limella n. sp., Leviella riedeli n. sp. Most assemblages point to neritic conditions in the photic zone. A similarity analysis demonstrates the distinct composition of reef-related and algae-related ostracod assemblages. The ostracod-algae associations in Lime Peak reveal that the affinity of Bairdiidae for algae (Dasycladaleans in the case of Lime Peak) was already established in the Norian. A faunal link is identified during the Norian between eastern and western Panthalassa and Japan, in line with studies on other taxa. The flux of species between eastern Panthalassa and Tethyan areas appears very unbalanced in the Late Triassic with most migrations originating from the Tethys. Further data from other Middle and Upper Triassic Panthalassan localities and stages (i.e. Ladinian and Carnian) are needed to confirm whether this apparent trend is due to sampling bias or reflects real dispersal fluxes.

  • MARINE LIFE IN THE MEDITERRANEAN DURING THE MESSINIAN SALINITY CRISIS: A
           PALEOICHTHYOLOGICAL PERSPECTIVE

    • Authors: GIORGIO CARNEVALE, WERNER SCHWARZHANS
      Abstract: Almost fifty years after the first definition of the Messinian salinity crisis (MSC), the events that occurred in the Mediterranean during the terminal portion of the Miocene still attract the attention of a large and diverse scientific community. Although fossils are relatively common in the deposits that accumulated during the MSC, their significance for the interpretation of the latest Miocene paleoenvironmental evolution of the Mediterranean has been underevalued. In this paper, we summarize the marine paleoichthyological record of the three stages of the MSC based on both articulated and isolated skeletal remains and otoliths, the latter almost exclusively known from the Lago-Mare phase. We focus on the composition of the marine ichthyofauna of the Mediterranean during the three main stages of the MSC, showing the persistent continuity of marine stenohaline taxa throughout most of the interval between 5.97 and 5.33 Ma. While the record of articulated fish skeletons is unquestionably autochthonous, thereby providing unambiguous evidence of the occurrence of open marine environments in the MSC preceding the Lago-Mare phase, the autochthonous nature of the otolith record has often been questioned. For this reason, the otolith record of marine fishes has been examined in detail from a taxonomic and paleoecological point of view. Three species, Bellottia verecunda n. sp., Benthosema taurinense n. sp., and Bostrychus marsilii n. sp., are described as new and a thorough discussion about the possible origin of the otoliths is provided. Alternative explanations for the occurrence of otoliths of marine fish during the Lago-Mare phase, such as reworking, contamination from overlying Pliocene sediments or import from outside the Mediterranean through aquatic birds are considered unlikely. In our assessment, the occurrence of marine fish otoliths in the Lago-Mare phase can be explained with the presence of normal marine environments in the Mediterranean, at least temporarily. Therefore, we suggest that the paleoichthyological data provided herein should be integrated in the future evolutionary paleoenvironmental reconstructions of the MSC.
