Pakicetus is an extinct genus of amphibious cetacean of the family Pakicetidae, which was endemic to Pakistan during the Ypresian (early Eocene) period, roughly 50 million years ago.[2] It was a wolf-like mammal,[3] about 1 metre (3 ft 3 in) to 2 metres (6 ft 7 in) long,[4] and lived in and around water where it ate fish and other animals. The vast majority of paleontologists regard it as the most basal whale, representing a transitional stage between land mammals and whales. It belongs to the even-toed ungulates with the closest living non-cetacean relative being the hippopotamus.[3]
