Proterosuchus fergusi, from the Early Triassic rocks of South Africa, is a pre-archosaur distantly related to the ancestors of modern crocodiles. Its skeleton shares many similarities with that of modern crocodiles, indicating that it led a similar lifestyle. It walked with its elbows-out in a semi-erect gait and was able to swing its long tail from side to side for swimming.

The long rows of simple cone-shaped teeth and the unusual down-turned “hook” at the end of the snout are interpreted as adaptations for catching and swallowing fish.
