Lissamphibiens de Dams (Quercy, SO France): Identification taxonomique et evolution durant la transition Eocene-Oligocene Open
International audience
Unveiling the First Neobatrachian (Anura) Discovered in the paleokarst system of Bolt’s Farm (Plio-Pleistocene; Cradle of Humankind), South Africa Open
Anurans are widely diversified in South Africa, with more than 150 recognised species across the country. However, most the known fossil records of anurans are concentrated in the southern part of South Africa, within the rich Pliocene sit…

Reinterpretation of tuberculate cervical vertebrae of Eocene birds as an exceptional anti‐predator adaptation against the mammalian craniocervical killing bite Open
We report avian cervical vertebrae from the Quercy fissure fillings in France, which are densely covered with villi‐like tubercles. Two of these vertebrae stem from a late Eocene site, another lacks exact stratigraphic data. Similar cervic…
A new pipid from the Cretaceous of Africa (In Becetèn, Niger) and early evolution of the Pipidae Open
Pipimorpha and its crown-group Pipidae possess one of the most extensive fossil records among anurans, known since the Early Cretaceous in both Laurasia and Gondwana. Pipimorph diversification may have been driven by the breakup of West Go…
The oldest articulated ranid from Europe: a <i>Pelophylax</i> specimen from the lowest Oligocene of Chartres-de-Bretagne (N.W. France) Open
Ranids represent an important part of the extant anuran diversity of Europe. One of the best-known genera is Pelophylax (green-water frog). This genus is considered to have arrived in Europe during the Eocene/Oligocene transition, with num…
Supplemental Data 1. The oldest articulated ranid from Europe: A Pelophylax specimen from the earliest Oligocene of Chartres-de -Bretagne (NW France) Open
Appendix for the article : The oldest articulated ranid from Europe: A Pelophylax specimen from the earliest Oligocene of Chartres-de -Bretagne (NW France)
A new genus and species of frog from the Kem Kem (Morocco), the second neobatrachian from Cretaceous Africa Open
Neobatrachia, a clade representing the majority of extant anuran diversity, is thought to have emerged and diversified during the Cretaceous. Most of the early diversification of neobatrachians occurred in southern Gondwana, especially the…

Conversion of the names Pyxicephaloidea, Pyxicephalidae and Pyxicephalinae (Anura, Ranoidea) into phylogenetic nomenclature Open
The recent publications of the sixth edition of the PhyloCode and of the monograph Phylonyms now allow the publication of nomenclatural acts that will establish priority under that code. This includes defining existing and newly proposed t…

From Toad to Frog, a CT-based Reconsideration of Bufo servatus , an Eocene Anuran mummy from Quercy (France) Open
In the XIXth century, natural mummies of amphibians were discovered inthe Quercy Phosphorites. The specific collection site was never formally reported, whichhampers precise dating of these specimens. Still, the name Bufo servatus was erec…
A new mineralized tissue in the early vertebrate<i>Astraspis</i> Open
The dermoskeleton of the earliest vertebrates is well known but their endoskeleton is thought to have been largely cartilaginous until the Late Silurian. We confirm that the dermal plates of Astraspis are three‐layered, with a superficial …
