jawbone in Peru picture

But Michael J. Ryan, head of vertebrate paleontology at the Cleveland Museum of Natural History, told National Geographic News that the bone is definitely not from a dinosaur. "It's a lower jawbone, and it has two big molars in the back and that's it. That's definitely a mammalian trait." he said after seeing the above photo of the find taken at a Tuesday press conference in Arequipa. "Also, the jaws are fused, left and right, and the massive shape and articulation mean it's definitely a mammal," he continued. Ryan thinks the remains most likely belonged to a proboscidean, or elephant relative.

"I can't even tell if it's fossil or modern," based on the photograph, Ryan added. But, he said, "there's no way it's a Triceratops."
