Large fossil whale

The giant 3-meter (10-foot) skull of what's been dubbed Leviathan melvillei (in honor of the author of "Moby Dick") was found with teeth in its top and bottom jaws up to 36 centimeters (14 inches) long. The discovery is reported in the July 1 issue of the journal Nature.

Living sperm whales have teeth only in their lower jaws and are specialized to feed on giant squid, Lambert explained. They suck down squid like large spaghetti noodles rather than catch the prey with their teeth. The much toothier fossil sperm whales, however, may have eaten more like a outsized-orca, or killer whale: chomping great big bites out of its prey.

"These are very unusual attributes," said cetacea evolution expert Ewan Fordyce of the University of Otago in New Zealand. "It's remarkably big. That is unexpected."

Another sign that this ancient whale had a killer bite is the large hole in the skull to accommodate a large jaw muscle. [1]
