Termatosaurus ("end lizard", because it came from the end of the Upper Triassic) is a genus of archosaur known from several specimens (only teeth are known) spanning two species. Its remains come from the Upper Triassic and was once thought to have survived until the Early Jurassic, but the Jurassic remains were redescribed as plesiosaur remains. It has only been found in France, England, Germany and Switzerland. and two species are known of this animal: the type species, Termatosaurus albertii, named by Meyer and T. Plieninger in 1844;[1] and T. crocodilinus, by Quenstedt (1858). It is very obscure and apparently considered to be dubious.[2]

According to Oskar Kuhn, Termatosaurus is a plesiosaur (of the Rhomaleosauridae),[3][4] while according to other sources, it is a phytosaur.[5] Currently, Termatosaurus is seen as a dubious archosaur.
