Emergence and ecological transition of the Mesozoic marine reptiles: Evidence from the Early Triassic Chaohu and the Middle Triassic Xingyi Faunas
Two major evolutionary events in the early history of Mesozoic marine reptiles have been recorded in the Triassic of China. The first event evidenced by the Early Triassic Chaohu Fauna was the emergence of new marine communities and their subsequent radiation in the Spathian Subage of the late Olenekian (Early...Jiang, Da-yong ; Zhou, Min ; Motani, Ryosuke ; Tintori, Andrea ; Fraser, Nicholas C …

New information on the protorosaurian reptile Macrocnemus fuyuanensis, Li et al., 2007, from the Middle/Upper Triassic of Yunnan, China
A new specimen of the protorosaur Macrocnemus fuyuanensis, from the Zhuganpo Member of the Falang Formation at Fuyuan (Yunnan Province, southwestern China), is described and compared with Macrocnemus bassanii. The new specimen is the first in the genus Macrocnemus that clearly shows details of the preorbital region of the skull....Jiang, Da-Yong ; Rieppel, Olivier ; Fraser, Nicholas C ; Motani, Ryosuke ; Hao, Wei-Cheng …

Tanystropheus cf. T. longobardicus from the Early Late Triassic of Guizhou Province, Southwestern China
The protorosaur Tanystropheus longobardicus is well known from the Middle Triassic of alpine Europe. It has been described on the basis of a number of specimens that apparently range from juvenile to adult. The largest specimens have a total body length of approximately 3 m. Here we report on the...Fraser, Nicholas C ; Rieppel, Olivier ; Jiang, Da-Yong ; Hao, Wei-Cheng ; Motani, Ryosuke …

A large aberrant stem ichthyosauriform indicating early rise and demise of ichthyosauromorphs in the wake of the end-Permian extinction
Contrary to the fast radiation of most metazoans after the end-Permian mass extinction, it is believed that early marine reptiles evolved slowly during the same time interval. However, emerging discoveries of Early Triassic marine reptiles are questioning this traditional view. Here we present an aberrant basal ichthyosauriform with a hitherto...Jiang, Da-Yong ; Motani, Ryosuke ; Huang, Jian-Dong ; Tintori, Andrea ; Hu, Yuan-Chao …
