An article published in the “Canadian Journal of Earth Sciences” describes a research on Ceratopsids, the so called horned dinosaurs that lived in the Late Cretaceous in today’s western areas of North America. A group of researchers led by Dr. Michael Ryan of the Cleveland Museum of Natural History, included some species into two new groups, or clades in technical jargon, called Nasutoceratopsini and Centrosaurini (Centrosaurinae).
