Reconstruction of Araripesuchus wegeneri, by Todd Marshall.

Belongs within: Crocodyliformes.
Contains: Neosuchia.

The Metasuchia were defined by Sereno et al. (2001) as the most exclusive clade containing both recent crocodilians and Notosuchus. This differs somewhat from its original usage by Benton & Clark (1988) for all members of the clade Mesoeucrocodylia excluding Thalattosuchia, which have subsequently been classified as derived metasuchians.

The Notosuchia are a group of often small, terrestrial crocodyliforms known from the Cretaceous of Africa and South America. Many notosuchians were markedly heterodont, with the rear teeth become multicusped and/or molariform (O’Connor et al. 2010). The Peirosauridae have been recognised as a group of moderately high-snouted crocodyliforms from the same time and area; it is possible that this group is paraphyletic to the later neosuchians (O’Connor et al. 2010).
