A paper in the Proceedings of the Royal Society B journal points to the existence of a 600kg (1322 lbs) amphibious whale-like animal that lived 43 million years ago. Named Phiomicetus anubis the discovery is based on fossil records discovered in Egypt’s Fayum Depression. The three-meter animals had “strong jaws” to catch their prey and had webbed feet to enable them to walk on land and swim underwater.
