==Discovery and naming== left|thumb|Polyphemus, mythological namesake of the species Bravoceratops is only known from the holotype specimen TMM 46015-1; it is housed in the collection of the Texas Memorial Museum, Austin, Texas. The skull consists of a number of fragments, altogether including: the , parts of each brow horn, the rear end of the left , assorted parts of the nasal area and horn, the , and quadratojugals from each side, a section of the and , multiple parts of the dentary, and some of the right . It was recovered from the lowermost rocks of the Javelina Formation, in Big Bend National Park; ceratopsid fossils are uncommon in this formation, giving the discovery of Bravoceratops importance in clarifying the groups' diversity. The specimen was found in sandy conglomerate sediment at the Hippiewalk geologic locality. Signs of erosion are presented in the larger bone fragments, which were found disorganized over an area of ten square metres; the site is thought to have been a lag deposit of a river, only most durable extremities able to survive preservation. The animal would have lived during the late Campanian or early Maastrichtian stage of the Cretaceous period, approximately 70 million years ago.
