Paleontologist hails discovery of cat-sized dinosaur

CHICAGO

Paleontologist Paul Sereno calls it a Pegomastax africanus, which means "thick jaw of Africa." And while Sereno is the first to describe the species, the fossils were actually excavated in the 1960's and kept at Harvard University.

Measuring about two feet long and weighing less than a house cat, he claims it would have looked like a "two-legged porcupine."
