Emergence, Extinction of Massive Ancient Shark to be Explored with NSF Grant

Forty million years after dinosaurs went extinct, one of the largest predators that ever prowled Earth’s oceans emerged, feeding the imaginations of modern scientists and the nightmares of modern movie audiences.

Megalodon — the name means ‘giant tooth’ — appeared some 23 million years ago and reigned the seas for about 21 million years. In 400 million years of shark evolution, megalodon is the most massive shark species that ever lived, growing to 60 feet long, or three times the size of the largest of today’s great whites.
