Pravusuchus

Description

Pravusuchus is an extinct genus of leptosuchomorph phytosaurid phytosaur known from the Late Triassic (Norian stage) of Arizona, United States. It contains a single species, Pravusuchus hortus, which is known from three specimens. These specimens were previously referred to Smilosuchus or to Leptosuchus, but Pravusuchus's autapomorphy, its phylogenetic position as well as a trait shared with pseudopalatines, justified the erection of a new taxon for the material.
