Phytosaurus

Phytosaurus (meaning "plant lizard") is a dubious genus of extinct parasuchid phytosaur found in an outcrop of the Keuper (likely the Exter Formation) in Germany. Phytosaurus was the first phytosaur to be described, being done so by Georg Friedrich von Jaeger in 1828. The type species is P. cylindricodon and a second species, P. cubicodon, is also known.

== Discovery and naming == thumb|200px|left|Associated elements from the holotype of P. cylindricodon In 1826, the holotypes of both species were discovered in Wurttemburg, Germany at the "Neckar" site at the base of the hill which Wildenau Castle stands upon. The holotype of P. cylindricodon consists of parts of the skull and jaws, with natural casts of the teeth which, however, did not preserve their conical form but were flattened which led to the misunderstanding they were specialised in eating plant material, and the holotype of P. cubicodon consists of fragments of the jaw. Both species were named and described by von Jaeger (1828) and were first commented on by von Meyer (1837).
