The Oldest Horned Dinosaur Ever Discovered In North America Is Tiny

Say hello to Aquilops americanus, the newest addition to the neoceratopsian family of horned dinosaurs. The diminutive creature, which was found in Montana, was no larger than a crow, sporting a beak-like nose and sharply pointed cavities on its cheeks.

Paleontologists working in southern Montana recently discovered a 3-inch beaked skull, which they believe is the oldest definitive evidence of a horned dinosaur in North America. The skull helps to fill gaps in the evolutionary history of horned creatures on this continent.
