Prolacerta and the protosaurian reptiles; Part II

Abstract

A second specimen of Prolacerta from the Lower Triassic of South Africa is closely related to Protorosaurus speneri. Since Prolacerta must remain closely associated with the Permian "Eosuchia" it now becomes necessary to place Protorosaurus in that group. It may be preferable to retain the old name Protorosauria in place of "Eosuchia." Prolacerta shows charactrs intermediate between Youngina and the lizards, also characters intermediate between Youngina and the rhynchocephalians. Prolacerta may be somewhat closer to the lizards as it seems to be incipiently streptostylic.
