Coahuilaceratops (meaning "Coahuila horn face") is a genus of herbivorous ceratopsian dinosaur. It is a chasmosaurine ceratopsian which lived during the Late Cretaceous period (late Campanian stage) in what is now southern Coahuila in northern Mexico. It is known from the holotype CPC 276, a partial skeleton of an adult individual which includes several skull elements. Another specimen, CPS 277, may represent a juvenile Coahuilaceratops. All specimens of Coahuilaceratops were collected from a single location in the Cerro del Pueblo Formation, dating around 72 million years ago.[1]
It was formally described in 2010, though it appeared as an informal designation (nomen nudum) as early as 2008.[2] Coahuilaceratops was named by Mark A. Loewen, Scott D. Sampson, Eric K. Lund, Andrew A. Farke, Martha C. Aguillón-Martínez, C.A. de Leon, R.A. Rodríguez-de la Rosa, Michael A. Getty and David A. Eberth in 2010 and the type species is Coahuilaceratops magnacuerna.[1] Although they are incomplete, Coahuilaceratops is thought to possess among the largest horns of any dinosaur currently known, rivaling in absolute size those of larger Chasmosaurines like Triceratops and Torosaurus. Its horns are estimated to have been up to 4 feet (1.2 m) long.[3][1]
