Time Period
Eocene Epoch

Basilosaurus was one of the first whales and the first whale fossils to be discovered. Basilosaurus was big: 15 to 20 meters long, or 49 to 66 feet! They were the apex predator of the Late Eocene Epoch, feeding on large fish and other marine mammals. The dolphin like cetacean dorundon was one of its favorite prey.

Basilosaurus was first discovered in the United States in the early 1800's. It was described in 1834. It was thought to be a reptile. It's name means King Lizard. Eventually we realized that basilosaurus was a mammal. Some even tried to rename it to reflect that understanding but the original name stuck. One of the interesting facts about basilosaurus is that it still had its hind legs! They were tiny and probably not very useful.

strangely enough, this marine mammal is from the order artiodactyl or even toed ungulates. Its ancestors were related to large grazing mammals like bison, giraffes, and elk. For some reason they returned to the sea and adapted to marine life.
