'Peculiar' crocodile ancestor started life on four legs before learning to walk on two

A “peculiar” ancient relative of the crocodile which experts believe began life on four legs before, in adulthood, it learned how to walk on just two has been revealed in a new study. Named Sonselasuchus cedrus, this archaic reptile was part of the shuvosaurid group, most of which had an appearance mimicking that of the ornithomimid dinosaurs that it shared the landscape with during the Late Triassic (approximately 225–201 million years ago).
