Megalodon was the largest of the sharks, living or extinct. They lived from 20 million years ago until about 1.5 million years ago. Scientist do not know precisely why the megalodon became extinct, but it was probably due to climate changes.
The megalodon skeleton was made of cartilage which does not fossilize easily. This means that the chances of finding a megalodon skeleton are slim. Thousands of teeth, however, are found throughout the world. They are serrated and though fossilized, are still sharp enough to inflict a severe wound.
