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.[1]
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.
Diet
Prenoceratops, like all ceratopsians, was a herbivore. During the Cretaceous, flowering plants were "geographically limited on the landscape", and so it is likely that this dinosaur fed on the predominant plants of the era: ferns, cycads and conifers. It would have used its sharp ceratopsian beak to bite off the leaves or needles.
