- A new species of ancient whale, Perucetus colossus, was a giant of the ocean.
- It may have weighed twice as much as a blue whale because of its dense bones.
- Researchers hypothesize that it was a slow swimmer that lived in coastal waters.
Roughly 39 million years ago, a slow-moving giant glided in shallow, coastal waters, potentially feeding on mollusks and crustaceans.
In 2010, paleontologist Mario Urbina found fossilized remains of this ancient animal, a new species of basilosaurid whale called Perucetus colossus.
The remains were unusual, gigantic bones in the Pisco Basin in southwestern Peru. The partial skeleton included 13 vertebrae, four ribs, and a hip bone.
