Systematics

First constructed in 2000, it was considered to include Notosuchus, Libycosuchus, and Sebecosuchia.^[1][2] In a 2004 phylogenetic study, it was defined as the most recent common ancestor of Notosuchus, Libycosuchus, and Baurusuchoidea and all of its descendants.^[3]

Ziphosuchia is often considered to be the sister group of Neosuchia, a clade that includes modern crocodilians. Razanandrongobe is the oldest representative of this clade.^[4]
