Aquatic habits and niche partitioning in the extraordinarily long-necked Triassic reptile Tanystropheus
Tanystropheus longobardicus is one of the most remarkable and iconic Triassic reptiles. Mainly known from the Middle Triassic conservation Lagerstätte of Monte San Giorgio on the Swiss-Italian border, it is characterized by an extraordinarily long and stiffened neck that is almost three times the length of the trunk, despite being... -

The first Triassic vertebrate fossils from Myanmar: Pachypleurosaurs in a marine limestone
As ecosystems recovered from the end-Permian extinction, many new animal groups proliferated in the ensuing Triassic. Among these were the sauropterygians, reptiles that evolved from terrestrial ancestors and transitioned to a marine environment. The first sauropterygians were small, marine-adapted taxa such as pachypleurosaurs, which are known from Middle–Late Triassic deposits,...San, Khaing Khaing ; Fraser, Nicholas C ; Foffa, Davide ; Rieppel, Olivier ; Brusatte, Stephen L

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 …

The earliest herbivorous marine reptile and its remarkable jaw apparatus
Newly discovered fossils of the Middle Triassic reptile Atopodentatus unicus call for a radical reassessment of its feeding behavior. The skull displays a pronounced hammerhead shape that was hitherto unknown. The long, straight anterior edges of both upper and lower jaws were lined with batteries of chisel-shaped teeth, whereas the...Chun, Li ; Rieppel, Olivier ; Long, Cheng ; Fraser, Nicholas C
