Archaeoceratops
Archaeoceratops, meaning "ancient horned face", was a genus of basal neoceratopsian dinosaur from the Early Cretaceous (Aptian stage) of north central China. It appears to have been bipedal and quite small (about 1 metre long) with a comparatively large head. Unlike many later ceratopsians it doesn't have any horns and has only a small bony frill projecting from the back of its head.
Discovery and Species
Two specimens were found in the Xinminbao Group,
The type specimen, IVPP V11114, consists of a partially complete skeleton including skull, caudal series (sequence of tail vertebrae), pelvis, and most of a hind pes (foot). The second specimen (paratype), IVPP V11115, consists of an incomplete skeleton with a relatively well preserved caudal series, a partial hind limb, and a completely preserved pes. It is slightly smaller than the holotype.
Archaeoceratops belonged to the Ceratopsia (the name is Greek for "horned face"), a group of herbivorous dinosaurs with parrot-like beaks which thrived in North America and Asia during the Cretaceous Period. In 1997 Dong and Azuma placed it in a new family, Archaeoceratopsidae.
Diet
Archaeoceratops, 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 beak to bite off the leaves or needles and chop them up to be swallowed.
