This material was studied by Lehman in 1989 and named Chasmosaurus mariscalensis. It is known only from the holotype UTEP P.37.7.086 a partial adult skull which includes a braincase, left supraorbital horncore, left maxilla and a right dentary. Additional material was associated with the holotype, but not considered to be part of it. All specimens of Agujaceratops were collected from the lower part of the Upper Shale member of the Aguja Formation, dating to about 77 million years ago, in the Big Bend National Park, Brewster County. Additional material was recovered from elsewhere in west Texas, including a nearly complete skull from Rattlesnake Mountain designated TMM 43098-1.
