Extinct Giant Whale-Eating Whale Found
- Unlike modern sperm whales, this one had teeth in both jaws and might have eaten like killer whales. - The 10-foot sperm whale skull fossil is the largest ever found. - Its main food might have been baleen whales. The massive skull and jaw of a 13-million-year-old sperm whale has been discovered eroding from the windblown sands of a coastal desert of Peru. The extinct cousin of the modern sperm whale is the first fossil to rival modern sperm whales in size -- although this is a very different beast, say whale evolution experts. "We could see it from very far," said paleontologist Olivier Lambert of the Muséum National d'Histoire Naturelle in Paris, France, who led the team which found the fossil.
