How long did the Megalodon live?
Megalodon was a long-lived animal. Scientists think that it lived for more than 100 years! Scientists think this because when paleontologists find fossilized vertebrae of Megalodon, they can determine the age of the animal when it died. Like the rings of a tree, shark vertebrae have bands that represent every year of the animal’s life. It is also possible to tell how fast the shark grew: the wider the band, the greater the growth.
