66-milion-year-old fossilized remains of this Dinosaur were unearthed in Wyoming provides proof that T. rex were cannibalistic in nature. In the analysis that was conducted later, the bone showed tooth marks that are typical with T. Rex's teeth, as per Matthew McLain, paleontologist at the Loma Lina University. He revealed his findings to the Geological Society of America's annual meeting on Sunday in Baltimore. The lead researcher told the Huffington Post, "We were very surprised to see tons of these tooth scores all over part of it. What's unique about this bone is you're not just seeing one bite, it looks like it was dragging its teeth several times. ... So we can be very confident about what animal was biting this."

According to the researchers, the bone that was discovered was broken at both the ends. They also said that the bone was covered in deep teeth marks of various sizes. In a report by Discovery News, it was revealed that the creature responsible for these teeth marks is likely to be T-rex. The teeth marks on the bone suggested that the creature's teeth were serrated. It could be the two legged therapoda who has such teeth, like the ones that were found on the ancient bone, says Perfect Science.

The lead author, Dr. Nick Longrich, was involved in the study conducted in 2010 but was not a part of the recent one. According to him, T. rexes fed on each other and said, "Cannibalism seems to be surprisingly common in these guys". "The main source of mortality for many predators is other members of their species -- alligators eat baby alligators, brown bears kill juvenile brown bears", reports Huffington Post.
