We think of dinosaurs roaming the earth and many of them were primarily land creatures but some of them were marine creatures as well. The biggest predatory marine creature to ever live was the Megalodon. The name Megalodon means “big tooth” in Greek. This dinosaur was a now extinct species of shark that lived 23 to 2.6 million years ago. Scientists say that the Megalodon probably looked like a much stockier version of the Great White Shark.
The Megalodon could reach a length of 59 feet long and their gigantic jaws could actually exert a bite force of up to 25,000 to 40,000 pounds of force. The Megalodon preferred and thrived in warmer waters and it is thought that the onset of the ice age coupled with lowering of sea levels and unavailability of proper nursing areas contributed to its extinction.
