Researchers at the University of Chicago announced today that they've discovered an identified a new dinosaur, Pegomastax africanus. According to 3D imaging done by researchers, the cat-sized dinosaur was covered in bizarre spines like a porcupine. The tall teeth in its upper and lower jaws operated like self-sharpening scissors, with shearing wear facets that slid past one another when the jaws closed.
Jackals from Halo, anyone?
