New material of Laophis crotaloides, an enigmatic giant snake from Greece, with an overview of the largest fossil European vipers

Georgalis, Georgios L. ; Szyndlar, Zbigniew ; Kear, Benjamin P. ; Delfino, Massimo

In: Swiss Journal of Geosciences, 2016, vol. 109, no. 1, p. 103–116

Laophis crotaloides was described by Richard Owen as a new and very large fossil viperid snake species from Greece. The type material is apparently lost and the taxon was mostly neglected for more than a century. We here describe a new partial viperid vertebra, collected from the same locality and of equivalent size to the type material. This vertebra indicates that at least one of the three...

A Review of the fossil record of turtles of the clade Pan-Kinosternoidea

Joyce, Walter G. ; Bourque, Jason R.

In: Bulletin of the Peabody Museum of Natural History, 2016, vol. 57, no. 1, p. 57–95

Turtles of the total clade Pan-Kinosternoidea have a relatively poor fossil record that extends back to the Late Cretaceous (Campanian). The clade is found only in North America during its early history, but dispersed to Central America no later than the Miocene and to South America no later than the Pleistocene. Ancestral pan-kinosternoids were likely aquatic, bottom-walking omnivores or...

First description of a fossil chamaeleonid from Greece and its relevance for the European biogeographic history of the group

Georgalis, Georgios L. ; Villa, Andrea ; Delfino, Massimo

In: The Science of Nature, 2016, vol. 103, no. 1–2, p. 1–12

The fossil record of Chamaeleonidae is very scarce and any new specimen is therefore considered important for our understanding of the evolutionary and biogeographic history of the group. New specimens from the early Miocene of Aliveri (Evia Island), Greece constitute the only fossils of these lizards from southeastern Europe. Skull roofing material is tentatively attributed to the Czech species...

A new Late Agenian (MN2a, Early Miocene) fossil assemblage from Wallenried (Molasse Basin, Canton Fribourg, Switzerland)

Mennecart, Bastien ; Yerly, Bertrand ; Mojon, Pierre-Olivier ; Angelone, Chiara ; Maridet, Olivier ; Böhme, Madelaine ; Pirkenseer, Claudius

In: Paläontologische Zeitschrift, 2016, vol. 90, p. 101-123

Excavations of two fossiliferous layers in the Wallenried sand- and marl pit produced a very diversified vertebrate fauna. New material allows the reassessment of the taxonomic position of the ruminant taxa Andegameryx andegaviensis and endemic Friburgomeryx wallenriedensis. An emended diagnosis for the second species is provided and additional material of large and small mammals, as well as...

Fossil and genetic evidence for the polyphyletic nature of the planktonic foraminifera ‘Globigerinoides’, and description of the new genus Trilobatus

Spezzaferri, Silvia ; Kucera, Michal ; Pearson, Paul Nicholas ; Wade, Bridget Susan ; Rappo, Sacha ; Poole, Christopher Robert ; Morard, Raphaël ; Stalder, Claudio

In: PLoS ONE, 2015, vol. 10, no. 5, p. e0128108

Planktonic foraminifera are one of the most abundant and diverse protists in the oceans. Their utility as paleo proxies requires rigorous taxonomy and comparison with living and genetically related counterparts. We merge genetic and fossil evidence of “Globigerinoides”, characterized by supplementary apertures on spiral side, in a new approach to trace their “total evidence phylogeny”...

A review of the fossil record of turtles of the clade Pan-Carettochelys

Joyce, Walter G.

In: Bulletin of the Peabody Museum of Natural History, 2014, vol. 55, no. 1, p. 3–33

Turtles of the total clade Pan-Carettochelys have a relatively poor fossil record that extends from the Early Cretaceous. The clade is only found in Asia during the Cretaceous, but spreads to Europe and North America during the Eocene. Neogene finds are restricted to Europe, Africa and Australia, whereas the only surviving species, Carettochelys insculpta, lives in New Guinea and the Northern...
