Dinocephalosaurus orientalis Li, 2003: a remarkable marine archosauromorph from the Middle Triassic of southwestern China
The non-archosauriform archosauromorph Dinocephalosaurus orientalis was first described from the Upper Member of the Guanling Formation (late Anisian, Middle Triassic) of Guizhou Province by Li in 2003 on the basis of a complete articulated skull and the first three cervical vertebrae exposed in dorsal to right lateral view. Since then,...Spiekman, Stephan N F ; Wang, Wei ; Zhao , Lijun ; Rieppel , Olivier ; Fraser, Nicholas C …

Hwiccewyrm trispiculum gen. et sp. nov., a new leptopleuronine procolophonid from the Late Triassic of southwest England
The fissure fill localities of southwest England and South Wales are well‐known for preserving rich assemblages of predominantly small‐bodied Late Triassic to Early Jurassic tetrapods, but many aspects of these assemblages remain contentious. The age of the Late Triassic fissures is disputed, with some lines of argument suggesting a latest...Butler, Richard J ; Meade, Luke E ; Cleary, Terri J ; McWhirter, Kai T ; Brown, Emily E …

Moray's Contribution to Pangaea and Triassic Park
Join Dr Nick Fraser as he explored Moray's Contribution to Pangaea and Triassic Park. The Triassic was a critical time for the evolution of life on Earth. This period witnessed the first appearance of some of the most successful animals that ever lived, including lizards, dinosaurs, turtles and crocodilians, the...Fraser, Nicholas C

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 postcranial remains from the Lealt Shale Formation of the Isle of Skye, Scotland, showcase hidden pterosaur diversity in the Middle Jurassic
The Early to Middle Jurassic transition was significant in pterosaur evolution, during which these volant reptiles exploded in diversity alongside dinosaurs and other animals. It has long been thought, however, that pterosaurs did not develop large wingspans until after the Jurassic, a notion challenged by the recent discovery of in...Jagielska, Natalia ; Challands, Thomas J ; O'Sullivan, Michael ; Ross, Dugald A ; Fraser, Nicholas C …

Scleromochlus and the early evolution of Pterosauromorpha
Pterosaurs, the first vertebrates to evolve powered flight, were key components of Mesozoic terrestrial ecosystems from their sudden appearance in the Late Triassic until their demise at the end of the Cretaceous1,2,3,4,5,6. However, the origin and early evolution of pterosaurs are poorly understood owing to a substantial stratigraphic and morphological...Foffa, Davide ; Dunne, Emma M ; Nesbitt, Sterling J ; Butler, Richard J ; Fraser, Nicholas C …

A new long‐necked archosauromorph from the Guanling Formation (Anisian, Middle Triassic) of southwestern China and its implications for neck evolution in tanystropheids
A long neck is an evolutionary innovation convergently appearing in multiple tetrapod lineages, including groups of plesiosaurs, non-archosauriform archosauromorphs, turtles, sauropodomorphs, birds, and mammals. Among all tetrapods both extant and extinct, two Triassic archosauromorphs, Tanystropheus and Dinocephalosaurus, have necks that are particularly elongated relative to the lengths of their trunks....Wang, Wei ; Spiekman, Stephan N F ; Zhao, Lijun ; Rieppel, Olivier ; Scheyer, Torsten M …
