After analyzing 7-million-year-old fossilized teeth, researchers have found that megalodon was a picky eater.
Paleontologists discovered that this massive creature preferred to eat only dwarf whales – and say this limited diet may have led to its demise some 2.6 million years ago.
The team suggests a cooling climate killed off megalodon’s food supply and it was unable to choose another prey to feed on.
Megalodon lived between 23 million and 2.6 million years ago and scientists have been baffled to why these creatures just disappeared from the planet.
‘The disappearance of the last giant-toothed shark could have been triggered by the decline and fall of several dynasties of small to medium-sized baleen whales in favor of modern, gigantic baleen whales,’ team leader Alberto Collareta from the University of Pisa, Italy, told Richard Gray with New Scientist.
