Pegomastax was only identified in the last few months, bringing a whole new world of weird into paleontology. Its mouth looks like a Medieval torture device, and paleontologists think its canine teeth sharpened themselves against each other. As if that's not weird enough, Pegomastax likely sported quills all over its body. Though it was about the size of a house cat, we sure wouldn't want to pet one. Artwork by Teratophoneus.
