Archosaurs, or ¨ruling reptiles,〃 first appeared during the Triassic, a period in Earthˇs history that lasted from 251 to 200 million years BC. Some archosaurs would have gradually abandoned the ¨crawling〃 stance, characterized by the belly hugging the ground and legs attached to the sides of the body (like modern crocodiles).
