FOSSIL CROCODYLIANS FORM THE EOCENE DEVIL'S GRAVEYARD AND CANOE FORMATIONS, BREWSTER COUNTY, TEXAS

摘要

Fragmentary crocodylian remains from the Lower Eocene of west Texas represent at least three taxa; these are the extinct generalized taxon Borealosuchus, the terrestrial Pristichampsus and a derived alligatorid closely resembling forms given the name Allognathosuchus. These remains are significant, as they preserve the youngest known Occurrence of Borealosuchus and may be the southernmost known occurrence of Allognathosuchus.
