Prestosuchids were a group of Triassic carnivorous archosaurs. They were large active terrestrial apex predators, ranging from around in length. They succeeded the Erythrosuchidae as the largest archosaurs of their time. While resembling erythrosuchids in size and some features of the skull and skeleton, they were more advanced in their erect posture and crocodile-like ankle, indicating more efficient gait. Prestosuchids flourished throughout the whole of the middle, and the early part of the late Triassic, and fossils are so far known from Europe, India, Africa (Tanganyika), Argentina,and Paleorrota in Brazil. However, experts disagree regarding the phylogenetic relationships of the group, what genera should be included, and whether indeed the Prestosuchidae constitute a distinct family apart from the Rauisuchidae.
