Ziphosuchia is a clade of mesoeucrocodylian crocodyliforms that includes notosuchians and sebecosuchians.
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]
