When did the Basilosaurus go extinct?
around 34 million years ago

‘Basilosaurus was a very strange animal, very long and snakelike,’ says Gingerich. Though similar in girth to today’s killer whales, Basilosaurus was more than twice their length (15 to 18 metres). Since these bones most likely contained marrow in life, they probably made Basilosaurus more buoyant.

Unlike modern cetaceans, the skull of Basilosaurus has bony external ear canals, suggesting that it may have retained some form of highly reduced external ear. The teeth in the tip of the snout are roughly similar to those of modern fish-eating toothed whales, although the teeth are extremely robust and deeply rooted.
Why did the Basilosaurus go extinct?
Basilosaurus was a specialized type of animal that did not give rise to any later whales. Abrupt global cooling of the Earth’s climate at the end of the Eocene coincided with changing ocean circulation. This led to the extinction of Basilosaurus and most archaic whales around 34 million years ago.
