Family Proterosuchidae

Chasmatosaurus

Proterosuchids lived a semi-aquatic, crocodile-like existence in a flood-plain pond environment, preying upon fish and labyrinthodont amphibians.  They were upto one and a half metres in length, and known from Africa, Europe, India, China, and Australia.  They were actually more primitive then any crocodile.  The Proterosuchids represent the ancestral lineage from which all other Archosaurs evolved.
