Additional remains of Erpetosuchus have been found in the New Haven Formation of Connecticut in the eastern United States, although they were not attributed to the species E. granti. The relationship of Erpetosuchus to other archosaurs is uncertain. In 2000 and 2002, it was considered a close relative of the group Crocodylomorpha, which includes living crocodylians and many extinct relatives. However, this relationship was questioned in a 2012 analysis that found the phylogenetic placement of Erpetosuchus to be very uncertain.
==Discovery== left|thumb|Life restoration The first remains of Erpetosuchus were found in the Lossiemouth Sandstone Formation in Scotland, dating back to the late Carnian stage of the Late Triassic. The holotype specimen is BMNH R3139 and consists of a skull and a partial postcranial skeleton.
