[1] It is defined as the most inclusive clade containing all crocodylomorphs more closely related to Crocodylus niloticus (the Nile Crocodile) than to Notosuchus terrestris.

[2] Members of Neosuchia generally share a crocodilian-like bodyform adapted to freshwater aquatic life, as opposed to the terrestrial habits of more basal crocodylomorph groups.

It is often identified as a member of Goniopholididae,[4] though this is disputed, and the taxon may lie outside Neosuchia, which places the earliest records of the group in the Middle Jurassic.

Several groups convergently evolved elongate gharial-like skulls, which makes determining phylogenetic relationships of these taxa problematic.
