Paleontologists find an ancient two-foot whale. Basiliosaurus is a transition whale between terrestrial and marine whales.

This animal lived 40 million years ago and had the appearance of a great snake.

When whale pioneers moved from land to water, they underwent changes in the body. The front feet became wings and the rear ones almost disappeared. Some whales still replace the old feet with two small nodules.
