A University of Chicago scientist says he's discovered a new dinosaur. 

Paul Serano says the "Pegomastax Africanus" would have looked something like a "two- legged porcupine."

He also says the animal was less than two-feet long and weighed less than a house cat. 

While Serano is the first to describe the species, it was actually excavated in the 1960s. 

Scientists say the dinosaur lived about 200 million years ago.
