The biggest shark attack in history did not involve humans.
A new study by Earth scientists from Yale and the College of the Atlantic has turned up a massive die-off of sharks roughly 19 million years ago. It came at a period in history when there were more than 10 times more sharks patrolling the world's oceans than there are today. For now, researchers don't know the cause of the shark die-off.
