A new short-bodied salamander from the Upper Jurassic-Lower Cretaceous of China

tom 51

nr 1

Abundant well−preserved salamander fossils have recently been recovered from localities across northeastern China. Pangerpeton sinensis gen. et sp. nov. is represented by a nearly complete skeletal impression of a postmetamorphosed salamander from the Late Jurassic/Early Cretaceous locality of Wubaiding, Liaoning Province. It is characterised by a short wide skull and only 14 presacral vertebrae. Associated soft tissue impressions suggest a warty skin and a broad body outline. Phylogenetic analysis indicates a basal position within Caudata, either just within or just outside crown−group Urodela.

New lizards and rhynchocephalians from the Lower Cretaceous of Southern Italy

The Lower Cretaceous (Albian age) locality of Pietraroia, near Benevento in southern Italy, has yielded a diverse assemblage of fossil vertebrates, including at least one genus of rhynchocephalian (Derasmosaurus) and two named lizards (Costasaurus and Chometokadmon), as well as the exquisitely preserved small dinosaur, Scipionyx. Here we describe material pertaining to a new species of the fossil lizard genus Eichstaettisaurus (E. gouldi sp. nov.). Eichstaettisaurus was first recorded from the Upper Jurassic (Tithonian age) Solnhofen Limestones of Germany, and more recently from the basal Cretaceous (Berriasian) of Montsec, Spain. The new Italian specimen provides a significant extension to the temporal range of Eichstaettisaurus while supporting the hypothesis that the Pietraroia assemblage may represent a relictual island fauna. The postcranial morphology of the new eichstaettisaur suggests it was predominantly ground−living. Further skull material of E. gouldi sp. nov. was identified within the abdominal cavity of a second new lepidosaurian skeleton from the same locality. This second partial skeleton is almost certainly rhynchocephalian, based primarily on foot and pelvic structure, but it is not Derasmosaurus and cannot be accommodated within any known genus due to the unusual morphology of the tail vertebrae.
