The Prestosuchids appear to be a sister group to the proper rauisuchians, branching off after the ornithosuchians. They were top carnivores in the Gondwana regions. But the phylogenetic relationships of the suchian archosaurs remain far less understood than the ornithodiran clade. Prestosuchus from south America has a skull (above) that is a meter long and might have been upto 5 meters in length preying vigorously on Triassic synapsids, dinosaurs and other reptiles.
