Rhynchosaurs (meaning "beaked lizards") were a group of unusual herbivorous quadrupedal archosauromorphs that lived during the Triassic period. Rhynchosaurs ranged in size from the 50 cm long Rhynchosaurus to the 2 meter (6 feet) long Hyperodapedon, with the average size being 1 meter (3.3 feet). Rhynchosaurs were a widespread and worldwide taxon, being found all across the supercontinent of Pangaea. Rhynchosaur fossils have been found in Britain, South Africa, Zimbabwe, Tanzania, Madagascar, India, Brazil, Argentina, Canada and the United States, although they are poorly represented in the Northern Hemisphere fossil record. 15 species are currently regarded as valid, and another five are valid taxa still in need of a name. In some fossil assemblages, several taxa lived alongside one anoth
