How was the Pakicetus discovered?
In 2001, Thewissen’s team discovered the skeleton of Pakicetus attocki, the oldest known whale, and published it as a cover-story in Nature. Pakicetus and Ambulocetus represent the two earliest stages of whales, and Indohyus complements this by showing it what the ancestors of whales looked like.
