From Wikipedia, the free encyclopedia
Pachystropheus is a genus of prehistoric reptile, probably a choristodere (champsosaur), from the Rhaetian (Late Triassic) of southwestern England. It was named by Friedrich von Huene in 1935; Huene described Pachystropheus as a champsosaur,[1] but this was overlooked for decades until its redescription by Storrs and Gower in 1993. This reevalution would extend the fossil record of champsosaurs back 45 million years.[2]
