[1] Clark's solution to this issue was to restrict the name Crocodylia to the group containing modern alligators, crocodiles, and gharials, plus any extinct taxa descended from their closest common ancestor.

Clark did not initially provide an exact definition for Crocodyliformes; but, in 2001, Paul Sereno and colleagues defined it as the clade including Protosuchus richardsoni and the Nile crocodile, plus all descendants of their common ancestor.

Tracks representing the ichnofamily Batrachopodidae are described from the Early Cretaceous (late Aptian) Calonda Formation (Angola) by Mateus et al. (2017), who name a new ichnotaxon Angolaichnus adamanticus.

[8] Terrestrisuchus Dibothrosuchus Gobiosuchus Zaraasuchus Orthosuchus Protosuchus Hemiprotosuchus Kayenta Form Edentosuchus Mesoeucrocodylia In 2012, paleontologists Mario Bronzati, Felipe Chinaglia Montefeltro, and Max C. Langer conducted a broad phylogenetic analysis to produce supertrees of Crocodyliformes, including 184 species.
