Dorudon - Wikipedia
Dorudon ("spear-tooth") is a genus of extinct basilosaurid ancient whales that lived alongside Basilosaurus 40.4 to 33.9 million years ago in the Eocene. It was a small whale, with D. atrox measuring 5 metres (16 ft) long and weighing 1–2.2 metric tons (1.1–2.4 short tons). Dorudon lived in warm seas around the world and fed on small fish ...
