Oldest horned dinosaur in North America discovered

Paleontologists have identified the fossil of a horned dinosaur the size of a crow that is the oldest of its kind ever discovered in North America.Scientists discovered the dinosaur skull in Montana that represents the first horned dinosaur from the North American Early Cretaceous that they can identify to the species level.Andrew Farke from Raymond M Alf Museum of Paleontology and colleagues named the dinosaur Aquilops americanus, which exhibits definitive neoceratopsian features and is closely related to similar species in Asia.The skull is comparatively small, measuring 84 mm long, and is distinguished by several features, including a strongly hooked rostral bone, or beak-like structure, and an elongated and sharply pointed cavity over the cheek region.
