  • Amphibian and reptilian fauna from the early Miocene of Echzell,

    • Abstract: Fossil Record 25(1): 99-145
      DOI : 10.3897/fr.25.83781
      Authors : Davit Vasilyan, Andrej Čerňanský, Zbigniew Szyndlar, Thomas Mörs : The present study describes a rich amphibian and reptilian assemblage from the early Miocene locality Echzell, Germany. It consists of one allocaudate, five salamander, five frog, one gecko, chamaeleonids, anguine lizards, one lacertid, one skink and five snake taxa. The entire herpetofauna of Echzell is represented by genera and/or families very broadly known from the early Miocene of Europe. Contrary to other early Miocene herpetofaunas, the Echzell assemblage includes surprisingly only one form of crocodile-newts (Chelotriton). The Echzell Palaeobatrachus robustus represents the youngest record of the species and extends its stratigraphic range to the late early Miocene. Regarding chameleons, the frontal is partly preserved, but represents the first described frontal of the extinct species Chamaeleo andrusovi. The only anguine lizard that can be identified in the assemblage is represented by a new genus and species Smithosaurus echzellensis. Our phylogenetic analyses consistently recovered it as the sister taxon to either [Ophisauriscus quadrupes + Ophisaurus holeci] + [Anguis + Ophisaurus] (in the first analysis) or [Anguis + Ophisaurus] (in the second analysis). However, the results are based on limited fossil material – the parietal – and the support for the clade is very low. Thus, the interpretation of the Smithosaurus relationship among anguines needs to be taken with caution and has to be tested in further studies. Among snakes, Natrix longivertebrata represents the oldest record of the species and extends the stratigraphic range of this fossil snake back to the early Miocene. In addition, we provide here a broader comparison of the Echzell amphibian and reptilian assemblage with their European records for the MN3 and MN4 biostratigraphical units. Besides that, the entire herpetofauna of Echzell includes very broadly known early Miocene European forms. Remains of other groups of the same period such as Bufonidae, Hylidae, Pelodytidae, Amphisbaenia, Varanidae, Cordylidae, Pseudopus, are not found in the material available to us. We also conclude that the amphibian and reptilian fossil record across MN3–MN4 is significantly biased by taphonomic and/or environmental conditions. The amphibian and reptilian assemblage of Echzell is rich in forms living in humid and warm environments with forested areas, permanent water bodies and also some open habitats. The following climatic parameters can be reconstructed based on the herpetofauna: a mean annual temperature of 17.4–28.8 °C, minimal warm month temperature 18–28.3 °C, minimal cold month temperature 8–22.2 °C, and mean annual precipitation with a value of 791±254 mm.

  • Fossil assemblage from the Khok Pha Suam locality of northeastern,
           Thailand: an overview of vertebrate diversity from the Early Cretaceous
           Khok Kruat Formation (Aptian-Albian)

    • Abstract: Fossil Record 25(1): 83-98
      DOI : 10.3897/fr.25.83081
      Authors : Sita Manitkoon, Uthumporn Deesri, Komsorn Lauprasert, Prapasiri Warapeang, Thanit Nonsrirach, Apirut Nilpanapan, Kamonlak Wongko, Phornphen Chanthasit : The Khok Pha Suam locality in the province of Ubon Ratchathani, northeastern, Thailand, is known as “the last home of Thai dinosaurs”, because it belongs to the Lower Cretaceous Khok Kruat Formation (Aptian-Albian) which is currently the youngest Mesozoic vertebrate fossil producing formation in the Khorat Group. Here, we describe a diverse vertebrate assemblage, including hybodonts, ray-finned fishes, turtles, crocodyliforms, pterosaurs, and dinosaurs from the Khok Pha Suam locality. The updated data on the Khok Kruat fauna provides a better understanding of the variety and distribution of Early Cretaceous continental ecosystems, which are useful for palaeoenvironmental reconstruction. In addition to consolidating unincorporated data on fauna, this study also provides the palaeontological data necessary to illustrate the palaeoecosystem to the general public, as well as improving the academic value of the Pha Chan-Sam Phan Bok Geopark.

  • Bizarre egg structure uncovers a new family of Plecoptera (Insecta)
           from mid-Cretaceous Burmese amber

    • Abstract: Fossil Record 25(1): 75-82
      DOI : 10.3897/fr.25.81862
      Authors : Zhi-Teng Chen : A new fossil stonefly, Perspicuusoperla lata gen. et sp. nov., is described and illustrated based on a well-preserved female adult and its eggs in mid-Cretaceous Burmese amber. The new taxon exhibits a combination of diagnostic morphologies, such as two crossveins between anterior radius (RA) and posterior radius (RP), broad subgenital plate exceeding abdomen tip, and entirely membranous eggs that cannot be incorporated into any known stonefly families. Perspicuusoperlidae, fam. nov. is established based on Perspicuusoperla gen. nov. and its systematic position is preliminarily discussed based on morphological comparison with other stoneflies. Palaeobiological implications are inferred from the egg morphology. This study represents the earliest known and best-preserved fossil record of extinct stonefly eggs. HTML XML PDF

  • First fossil species of ship-timber beetles (Coleoptera, Lymexylidae)
           from Eocene Rovno amber (Ukraine)

    • Abstract: Fossil Record 25(1): 65-74
      DOI : 10.3897/fr.25.81054
      Authors : Shûhei Yamamoto, Vitaly Yu. Nazarenko, Dmitry V. Vasilenko, Evgeny E. Perkovsky : A new lymexylid fossil species, †Raractocetus sverlilo Nazarenko, Perkovsky & Yamamoto, sp. nov., is described from late Eocene Rovno amber of Ukraine. This new species is similar to species of the recent genera Atractocerus Palisot de Beauvois and Raractocetus Kurosawa in the ship-timber beetle subfamily Atractocerinae, but differs in pronotal and elytral features. Notably, the new species is one of the smallest atractocerines known to date. This is the first member of the family Lymexylidae found in Rovno amber. Our finding sheds further light on the paleodiversity of atractocerine beetles, highlighting a peculiar distribution during the Eocene. Only one extant atractocerine specimen has been reported from Europe (Greece), while three species from Eocene European amber forests with equable climate are known now, including two species from the otherwise tropical genus Raractocetus. Our finding of the Raractocetus beetle from Rovno amber is of significant biogeographically because it indicates the wide distribution of the genus in the Eocene European amber forests. HTML XML PDF

  • Hypothesis testing on the planktic foraminiferal survival model after
           the KPB mass extinction: evidence from Tunisia and Algeria

    • Abstract: Fossil Record 25(1): 43-63
      DOI : 10.3897/fr.25.79958
      Authors : Ignacio Arenillas, José A. Arz, Fariza Metsana-Oussaid, Vicente Gilabert, Djelloul Belhai : A historical review of the extinction, survival, and evolutionary models of planktic foraminifera proposed for the Cretaceous/Paleogene boundary (KPB) mass extinction event sometimes leaves the impression that there is still no conclusive evidence to support any single one of them. Two main models have been put forward: i) catastrophic mass extinction, almost total for some authors, compatible with the geologically instantaneous paleoenvironmental effects of a large meteorite impact (Chicxulub impact, Mexico); and ii) gradual mass extinction, compatible with the paleoenvironmental effects of massive, long-lasting volcanism (Deccan Traps, India). Over the years, a lot of evidence has been proposed supporting one hypothesis or the other, highlighting isotopic (δ18O, δ13C, 87Sr/86Sr) as well as taphonomic, biostratigraphic, quantitative (relative and/or absolute abundance), phylogenetic, and even teratological. We review previous planktic foraminiferal and stable isotope studies, and provide new quantitative and statistical tests from two pelagic sections: the El Kef section (Tunisia), recognized as the most continuous and expanded lowermost Danian section worldwide, and the Sidi Ziane section (Algeria), affected by relevant hiatus in the lower Danian. The results indicate that all the latest Maastrichtian planktic foraminiferal species except those of Guembelitria went extinct exactly at the KPB, supporting the hypothesis of an almost total extinction. In the light of this new evidence, we maintain that the Maastrichtian planktic foraminiferal specimens found worldwide in lower Danian samples could be the result of similar reworking and vertical mixing processes to those at El Kef and Sidi Ziane.

  • Deciphering the morphological variation and its ontogenetic dynamics in
           the Late Devonian conodont Icriodus alternatus

    • Abstract: Fossil Record 25(1): 25-41
      DOI : 10.3897/fr.25.80211
      Authors : Catherine Girard, Anne-Lise Charruault, Thomas Gluck, Carlo Corradini, Sabrina Renaud : Identification of relevant taxonomic and evolutionary units is a recurrent issue in the fossil record, and all the more for ancient fossils devoid of modern equivalents such as conodonts. Extensive morphological variation has often led to the description of numerous species, subspecies or morphotypes, which may correspond to end-member morphologies reached through ontogeny. The platform elements of the Late Devonian conodont species Icriodus alternatus were characterized by rows of denticles coming into occlusion between opposite elements; each element grew by the incremental addition of lamellae and by the addition of successive triads during ontogeny. During the late Frasnian and the early Famennian, the important morphological variation within this species led to the description of three subspecies. An extensive sample of early Famennian Icriodus alternatus was quantified using 2D biometric measurements and denticle counts on 2D pictures, showing that the subspecies mainly differed in their size range but not in their general morphology. A 3D morphometric analysis was further performed on a subsample to characterize the shape of the ontogenetically older part of the elements. During ontogeny, early valleys between denticles tended to be filled, and the asymmetry between the inner and outer side of the element increased. These ontogenetic trends are responsible for the morphologies formerly described as the subspecies Ic. alt. mawsonae and Ic. alt. helmsi. Slight discrepancies between temporal ranges of the subspecies may be achieved through variations in range of size reached by the elements as a response to environmental changes. Disparity along ontogeny seems to follow an “hourglass model” suggesting a shift from relatively loose developmental constraints to a pattern of growth modulated by functional constraints during occlusion.

  • The first adult mantis lacewing from Baltic amber, with an evaluation
           of the post-Cretaceous loss of morphological diversity of raptorial
           appendages in Mantispidae

    • Abstract: Fossil Record 25(1): 11-24
      DOI : 10.3897/fr.25.80134
      Authors : Viktor Baranov, Ricardo Pérez-de la Fuente, Michael S. Engel, Jörg U. Hammel, Christine Kiesmüller, Marie K. Hörnig, Paula G. Pazinato, Corleone Stahlecker, Carolin Haug, Joachim T. Haug : Mantis lacewings (Neuroptera: Mantispidae) are prominent and charismatic predatory representatives of Insecta. Nevertheless, representatives of the group are surprisingly scarce in Paleogene deposits after a relative abundance of specimens known from Cretaceous. Here we present Mantispa' damzenogedanica sp. nov., representing the first adult of Mantispidae described from Baltic amber and the only Eocene adult mantispid hitherto preserved in amber. The new fossil species is also among the earliest representatives of Mantispinae, certainly the oldest adult of this group described from amber. Additionally, we discuss the changes through time in the ecological morphospace within Mantispidae based on the morphological diversity (≈disparity) of the raptorial legs. Possible explanations for the post-Cretaceous decline in the morphological diversity of mantis lacewings are posited. HTML XML PDF

  • A neomorphic ossification connecting the braincase, squamosal, and
           quadrate in choristoderan reptiles: insights from µCT data

    • Abstract: Fossil Record 25(1): 1-10
      DOI : 10.3897/fr.25.79595
      Authors : Wanying Qin, Hongyu Yi, Keqin Gao : Choristoderes are extinct semi-aquatic to aquatic diapsid reptiles, occupying a similar niche as modern crocodilians from the Jurassic to the Miocene. Distinct from other diapsids, choristoderes have a neomorphic ossification between the braincase, squamosal, and quadrate. This neomorphic bone is described as thin and plate-like in long-snouted choristoderes (Neochoristodera), yet little is known about its presence and morphology in short-snouted non-neochoristoderes that are sister groups to Neochoristodera. Using X-ray micro-CT scanning, this study describes in detail the neomorph of two non-neochoristoderes, Coeruleodraco jurassicus and Philydrosaurus proseilus. The neomorph of both species is found between the parietal, quadrate, and squamosal. The shape of the neomorph resembles a pyramid in three-dimensions, with a triangular dorsal surface and a prominent ventral process. This confirms the neomorph is shared among early and late branching choristoderes; therefore, presence of the neomorph is a potential synapomorphy of Choristodera. In addition, the pterygoquadrate foramen is identified in non-neochoristoderes for the first time, located between the neomorph and quadrate in C. jurassicus. In the holotype of P. proseilus, the neomorph and quadrate were dislocated, but a possible pterygoquadrate foramen is identified between the two bones. Although the neomorph and pterygoquadrate foramen have been suggested to be homologous with the stapes and stapedial foramen in Champsosaurus, more evidences are required to confirm this homology in non-neochoristoderes, because 1) the neomorph is long and plate-like in neochoristoderes, but pyramid-shaped in non-neochoristoderes; 2) in Champsosaurus, the neomorph is situated lateral to the prootic and opisthotic; in C. jurassicus and P. proseilus, articulation between the neomorph and prootic (or opisthotic) cannot be confirmed due to damage to the braincase during preservation. To understand the origin of the neomorph, more intact specimens are needed to assess contact relationships between the neomorph and otic region in non-neochoristoderes. HTML XML PDF
