Researchers upon analysis of bite marks on fossilized bones have come up with new findings. As per it, the prehistoric super predator, the Tyrannosaurus Rex, might have eaten its own kind as well as had gorged on other preys.

The chewed bone dating back 66 million years ago found in Lance Formation, Wyoming, owing to which the researchers have come to know about the cannibalistic behavior of T-rex will be presented at the annual Geological Society of America meeting in Baltimore, Maryland.

The researchers said marks on bones were made by serrated teeth. According to study researcher Matthew McLain, the only one that could have made such marks was another T.rex. Explaining about the condition of the found bone, McLain said that the bone was broken from the corners and it clearly showed that a big-sized predator has torn apart the flesh.

Presence of small gouges on one end indicates that the predator had turned its head while eating. The researchers said that it is not the first time when it has been found that a T.rex has eaten its own kind. Debates have taken place on whether T.rex was a hunter or scavenger.

There has been mixed response on it. In fact, a study carried out in 2012 has estimated that the force of a T.rex bit is around 57,000 Newtons or 12, 800 pounds. This much amount is sufficient to tear apart a large dinosaur like T.rex.
