Prenoceratops

Prenoceratops, (meaning 'bent or prone-horned face' and derived from Greek prene-/πρηνη- meaning 'bent forwards' or 'prone', cerat-/κερατ- meaning 'horn' and -ops/ωψ meaning 'face') is a genus of ceratopsian dinosaur from the Late Cretaceous Period. Its fossils have been found in the upper Two Medicine Formation in the present-day U.S. state of Montana, in Campanian age rock layers that have been dated to 74.3 million years ago.

Discovery and species
Prenoceratops was first described by Brenda J. Chinnery in 2004. It is unusual in that it is the only basal neoceratopsian known from a bonebed.

Prenoceratops species include P. pieganensis (type).

Classification
Prenoceratops belonged to the Ceratopsia (which name is derived from Ancient Greek, meaning 'horned face'), a group of herbivorous dinosaurs with parrot-like beaks, which thrived in North America and Asia during the Cretaceous Period. It is closely related to Leptoceratops, which it antedates by several million years. It is characterized by a lower, more sloping head than that of Leptoceratops.
