Some 60 years ago, hundreds of dinosaur bones belonging to Coelophysis were discovered in a site north of Santa Fe, New Mexico. Some fossils showed what appeared to be baby Coelophysis inside the grown-up Coelophysis, so paleontologists declared the species cannibals.

But the dino species may yet redeem its reputation as new fossil study suggests they didn't snack on their own young. "Our research shows that the evidence for cannibalism in Coelophysis is nonexistent," according to a team at Columbia University in New York City.

A new fossil suggests what's inside the Coelophysis could, in fact be, crocodiles or some related species. In another discredited evidence, the baby inside the adult was simply too big to fit in. Paleo-CSI agents now think the two bones had mingled during the event that caused the mass extinction. This gave the impression that adult Coelophysis practiced cannibalism.
