Aquilops americanus, by the incomparable Brian Eng.
There's a new basal neoceratopsian in town. It's from Montana's Cloverly Formation, and it's a raccoon-sized critter that is the oldest definitive horned dinosaur in North America: Aquilops americanus, an eagle-faced cutie. It was described by Andy Farke, Desmond Maxwell, Richard Cifelli, and Matthew Wedel. Andy wrote about it at The Integrative Paleontologist, and Matt Wedel has been covering it extensively--as well as public outreach--at SV-POW. Check it all out.
