These ancient beasts would have feasted on whales, large fish and other sharks, using their serrated teeth to shred their hapless victims.
Their meals would have consisted of animals ranging in size from dolphins to humpback whales.
The Natural History Museum’s Emma Bernard explained: “If you are that big you need to eat a lot of food, so large prey is required.”
Although the scientists have been unable to specify when exactly the shark attack occurred, it would have taken places along the coasts of what is now North Carolina.
According to Dr Godfrey, these coastal waters were relatively shallow and teeming with sea life.
