Biostratigraphy of new pterosaurs from China

  title={Biostratigraphy of new pterosaurs from China},
  author={Shu-an Ji and Qiang Ji and Kevin Padian},
Pterosaurs are represented in China by five genera and some isolated bones ranging in age from the Middle Jurassic to the Late Cretaceous period. Four of these genera belong to the derived monophyletic subgroup Pterodactyloidea; only the Middle Jurassic Angustinaripterus from Dashanpu, Sichuan, is a non-pterodactyloid (traditionally ‘rhamphorhynchoids’, a paraphyletic taxon). Two further pterosaurs (Fig. 1) from the Chaomidianzi Formation of the Beipiao area, western Liaoning Province, occur in… 
A eutherian mammal from the Early Cretaceous of Russia and biostratigraphy of the Asian Early Cretaceous vertebrate assemblages
Prokennalestes abramovi n.sp. is described based on M2 from the upper Barremian-middle Aptian (Early Cretaceous) Mogoito locality in Transbaikalia, Russia. It differs from the Mongolian species of
Pterosaur diversity and faunal turnover in Cretaceous terrestrial ecosystems in China
Two new pterosaurs that are referred to European groups previously unknown in deposits of northeastern China are reported, showing a wide range of groups including both primitive and derived forms that are not matched by any other deposit in the world.
New toothed flying reptile from Asia: close similarities between early Cretaceous pterosaur faunas from China and Brazil
The new species is closely related to a rare taxon from the Brazilian Crato Formation, posing an interesting paleobiogeographic problem and supporting the hypothesis that at least some early Cretaceous pterosaur clades, such as the Tapejaridae and the Anhangueridae, might have originated in Asia.
A new pterosaur (Pterodactyloidea, Tapejaridae) from the Early Cretaceous Jiufotang Formation of western Liaoning, China and its implications for biostratigraphy
In this article we describe a new and exceptionally well-preserved pterodactyloid pterosaur,Sinopterus dongi gen. et sp. nov. from the Jiufotang Formation in western Liaoning Province of northeast
A New Non-Pterodactyloid Pterosaur from Qinglong County, Hebei Province of China
: A new basal non-pterodactyloid pterosaur, Changchengopterus pani gen. et sp. nov., is erected, on the basis of a nearly complete postcranial skeleton. The new taxon is distinguished by
A New Ornithocheirid from the Early Cretaceous of Liaoning Province, China
Based on a nearly complete skeleton with skull from the Early Cretaceous of Liaoning Province, a new omithocheirid pterosaur: Boreopterus cuiae gen. et sp. nov. is erected. Boreopterus cuiae is
A revision of the putative Late Cretaceous triconodonts from South America
Austrotriconodon mckennai and Austrotriconodon sepulvedai, from the Campanian Los Alamitos Formation, Patagonia, Argentina were originally described as triconodont mammals and the sole members of the
A new eutriconodont mammal from the early Cretaceous Jehol Biota of Liaoning, China
A new genus and species of eutriconodont mammal, Chaoyangodens lii gen. et sp. nov., from the Dawangzhangzi bed of Yixian Formation, Lingyuan, Liaoning, is reported. The new species has a tooth
Cratostracus? cheni, a new conchostracan species from the Yixian Formation in western Liaoning, north-east China, and its age implications
The conchostracan genus Cratostracus was described from the Cenomanian Qingshankou Formation that crops out in the Jilin and Heilongjiang provinces of China, and species attributable to it have been
A new family of primitive mammal from the Mesozoic of western Liaoning, China
A fairly well-preserved specimen of a new primitive mammal,Repenomamus robustus gen. et sp. nov., has been described from the Yixian Formation (Lower Cretaceous), western Liaoning, China. This animal


Two feathered dinosaurs from northeastern China
Current controversy over the origin and early evolution of birds centres on whether or not they are derived from coelurosaurian theropod dinosaurs. Here we describe two theropods from the Upper
An exceptionally well-preserved theropod dinosaur from the Yixian Formation of China
The two nearly complete skeletons of a small theropod that represent a species closely related to Compsognathus are described, Sinosauropteryx, which has the longest tail of any known theropid, and a three-fingered hand dominated by the first finger.
