"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,cite journal |last=von Huene |first=Friedrich |authorlink=Friedrich von Huene |year=1935 |title=Ein Rhynchocephale aus dem Rhat (Pachystropheus n. g.) |journal=Neües Jahrbuch fur Mineralogie, Geologie und Palaontologie |volume=74 |pages=441–447 |language=German ] 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.cite journal |last=Storrs |first=G.W. |coauthors=and Gower, D.J. |year=1993 |title=The earliest possible choristodere (Diapsida) and gaps in the fossil record of semi-aquatic reptiles |journal=Journal of the Geological Society |volume=150 |issue=6 |pages=1103–1107 |doi=10.1144/gsjgs.150.6.1103 ]
