3D modeling of giant megalodon shark reveals clues to the life of the super-predator that ruled the oceans 20 million years ago

Fossil evidence shows that ancient megalodon sharks could have eaten a whale-sized meal in less than five bites.

Three times the size of the great white sharks were found in the 3D models created for the study.

The sharks would have weighed around 70 tons if they were alive today.

The research shows that the fish swam faster than the sharks of today and would roam the oceans for months after eating ocean creatures using their teeth.

The beast was described as a "super-predator" by the co-author of the study.

The megalodon did not fossilize well, which made it difficult to create models, according to a paleontologist.

She said they had to use a collection of bones in a museum.
