dc.descriptionMentor: Dr. Patrick Druckenmiller; On the basis of a new measured section, the long-frilled horned dinosaur Coahuilaceratops magnacuerna (previously reported from the Campanian Cerro del Pueblo Formation, in Northeastern Mexico) is herein reassigned to the Maastricthian Cerro Huerta Formation. These are the first dinosaur remains reported from this geological unit. As a consequence, this reassignment makes Coahuilaceratops up to ~2 million years younger than previously thought. This is more consistent with the relatively derived phylogenetic position of Coahuilaceratops, with implications for the southern Laramidia hypothesis concerning the origin of the Triceratopsini.en_US
