Venaticosuchus is a genus of pseudosuchian archosaurs from the family Ornithosuchidae. Known from a single species, Venaticosuchus rusconii, this genus is described based on an incomplete skull and jaw (as well as a lost partial forelimb and osteoderms) collected from the Late Triassic (Carnian) Ischigualasto Formation in the Ischigualasto-Villa Unión Basin in northwestern Argentina, which was deposited around 230 million years ago. This fossil material has been termed the holotype specimen PVL 2578. Venaticosuchus incorporated a myriad of features present in the other two genera of ornithosuchids, Ornithosuchus and Riojasuchus. However, it also had several unique traits, relating to the lower jaw.[1]

Reconstructions of the jaw musculature of Venaticosuchus showed that it had a slow, strong bite, similar to those of herbivorous aetosaurs such as Desmatosuchus. Venaticosuchus and other ornithosuchids were likely specialized scavengers, due to a combinations of features which suggested that they ate meat but were poorly adapted for dealing with living prey.[2]
