Temporal range: Late Cretaceous
Chinnery & Horner, 2007
Cerasinops (meaning 'lesser horned face') was a small ceratopsian dinosaur. It lived during the Campanian of the late Cretaceous Period. Its fossils have been found in Two Medicine Formation, in Montana.
Cerasinops was named and described by Brenda Chinnery and Jack Horner in 2007 from a specimen (MOR 300) almost 80% complete. Cerasinops belonged to the Ceratopsia (the name is Ancient Greek for 'horned face'), a group of herbivorous dinosaurs with parrot-like beaks that thrived in North America and Asia during the Cretaceous Period. Within this group, it has been placed as a basal member of Neoceratopia, although the description is variable; at one point, it is explicitly assigned to Leptoceratopsidae, but in others, it is considered a sister taxon to Leptoceratopsidae, or as a neoceratopsian in general.
