The Megalodon (“Big Tooth”) shark was possibly the most fearsome ocean predator in earths history reaching lengths of over 50 feet. A member of an extinct species of megatooth shark (Otodontidae) that is considered to be the largest shark, as well as the largest fish, that ever lived. Studies estimate that adult body mass ranged from roughly 30 metric tons (66,000 pounds) to more than 65 metric tons (143,000 pounds), adult females being larger (in both length and mass) than adult males.
Fossils attributed to megalodon have been found dating from the early Miocene Epoch (which began 23.03 million years ago) to the end of the Pliocene Epoch (2.58 million years ago).
