Cannibalism in the animal world may seem creepy to us, but there are certain species that have no problem chowing down on their own kind. It seems that cannibalism wasn’t out of the question 66 million years ago either.

A recently unearthed tyrannosaur bone with peculiar teeth marks appears to have been gnawed on by another tyrannosaur. According to a statement from the Geological Society of America (GSA), “The find could be some of the best evidence yet that tyrannosaurs were not shy about eating their own kind.”

Still hungry? Sink your teeth into more.
