Mystriosuchus (meaning "spoon-crocodile")[1] is an extinct genus of phytosaur that lived in the Late Triassic (middle Norian) in Europe. It was first named by Eberhard Fraas in 1896, and includes two species: M. westphali (formerly M. plieningeri) and the type species, M. planirostris.[2]
Description
Mystriosuchus planirostris measured about four metres long (13 ft), according to a complete skeleton which was found in 1995.[3] The postcranial anatomy of the skeleton suggests that Mystriosuchus was more adapted to aquatic life than other known phytosaurs,[3] while cranial morphology is suggestive of a primarily fish eating diet.[2]
Classification
Mystriosuchus used to be placed in its own subfamily, Mystriosuchinae,[4][5] however, recent research demonstratred that it belongs to the subfamily Pseudopalatinae, despite having several physical differences from most of the genera in this group.[2] Originally considered to be a freshwater genus, a recent specimen from Northern Italy has shown that some Mystriosuchus specimens lived a completely marine life.[3]
