Dorudon ("Spear-Tooth") was a genus of ancient cetacean that lived alongside Basilosaurus 41 to 33 million years ago, in the Eocene. They were about five meters (16 ft) long and were most likely carnivorous, feeding on small fish and mollusks. Prehistoric whales lived in warm seas around the world. Fossils have been found in North America, Egypt as well as Pakistan the eastern part of which bordered the ancient Tethys Sea.
