Ancient megalodon shark could eat a whale in a few bites, research suggests

Study used fossil evidence to create a 3D model of the 50ft-long shark and estimated it could have eaten a killer whale in five bites

Modern sharks have nothing on their ancient cousins. A giant shark that roamed the oceans millions of years ago could have devoured a creature the size of a killer whale in just five bites, research suggests.

For their study published on Wednesday, researchers used fossil evidence to create a 3D model of the megalodon - one of the biggest predatory fish of all time - and find clues about its life.
