It's always nice to put a face to a name---and not just in the case of humans. Paleontologist Paul Sereno just introduced the world to
a small two-legged dinosaur that lived 200 million years ago, traipsing through what is now South Africa armed with a pointed beak, unexpectedly sharp canine teeth, and a bristling coat of quills. Calling to mind an image of such an unusual animal is difficult (I come up with a sort of parrot-wolf-porcupine-raptor mix which, while intriguing, is certainly not correct). Luckily, however, there are people like Tyler Keillor, a paleoartist who builds lifelike models of ancient animals, letting us see them face to face rather than as a list of features. In the video above, he reconstructs P. africanus layer by layer, starting with a resin skull and adding clay muscles, all the way up intricately painted silicone rubber skin and fishing-line quills.
