Megalodon. Five Facts: Megalodon

Most megalodon teeth are 4 to 5 inches long. Over the years the size estimations of the Megalodon shark have changed, as the science surrounding it's evolution has progressed.

The Megalodon shark has first shown up around 23 million years ago and ruled the oceans till 3.

While our bones are coated in the mineral calcium phosphate, shark skeletons are made entirely from softer cartilage like our nose and ears.

In order to show the large teeth, the model is displayed with its mouth open.

How Are Megalodon Teeth Measured? Scientists calculate that a bite from a megalodon jaw could generate force of up to 40,000 pounds, which would make it the strongest bite in the entire animal kingdom. Using that tooth to determine the body size of the animal is something that has been done in living sharks today, and those calculations were then used to determine an overall, expected size for Megalodon. Whereas Great Whites dive straight toward their prey's soft tissues say, a carelessly exposed underbelly or the legs of a wading swimmer , Megalodon's teeth were especially suited to biting through tough cartilage, and there's some evidence that this giant shark may have first sheared off its victim's fins rendering it unable to swim away before lunging in for the final kill.

Modern scientific studies have shown that megalodon was more closely related to an ancestor of mako sharks—smaller but faster fish-eating sharks.

Scientists who have been studying modern sharks are working with paleontologists to study megalodon and other long-extinct shark species.

It is likely that the giant megalodon was unable to sustain its massive body size due to these changes and the loss of prey, and eventually went extinct.
