Sereno told WBBM Newsradio’s John Cody, others have collected and examined the bones, but he was fortunate to recognize the fact that the bones represented a brand new species.

Sereno says Pegomastax had a short parrot-shaped beak up front, a pair of stabbing canines, and tall teeth at the back of the jaw for slicing plants.

The parrot-shaped skull, less than three inches long, may have been adapted to eating fruit.

But Sereno says microscopic examination of the teeth suggested they were more for display and maybe defensive nipping, than actually cutting or tearing as would be expected from a carnivore.
