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 herbivorous ceratopsian dinosaur from the Late Cretaceous Period. It was a relatively small dinosaur, reaching in length and in body mass. 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. Fossils were also found in the Oldman Formation in the modern day Canadian province of Alberta, dating to around 77 million years ago.

==Discovery and species== thumb|left|Restoration Prenoceratops was first discovered on a Blackfeet reservation in Pondera County, Montana in layers coming from the Campanian Two Medicine Formation. The locality at which Prenoceratops was found was filled with many disassociated fossil elements of many individuals, known as a bonebed, though only the skull material has been described as of 2022. The holotype was one of the few associated specimens, including a surrangular fused with an articular, the specimen is designated as TCM 2003.1.1. Prenoceratops was later described by Brenda J. Chinnery in 2004, though the taxon has been little noticed since. It is unusual in that it is the only basal neoceratopsian known from a bonebed and the sheer number of elements.
