Brachyceratops
Dubious genus of reptiles (fossil)
Brachyceratops ('short horned face') is a dubious genus of ceratopsian dinosaur from the late Cretaceous Period of Montana, United States. Brachyceratops has historically been known from juvenile remains, with one specimen having since been re-classified as Rubeosaurus ovatus.
History of discovery
Brachyceratops montanensis, the type species, was first discovered in the Two Medicine Formation (Campanian, about 74 million years old) on a Blackfoot Indian Reservation in Teton County in north-central Montana. The original find was made in August 1913 by C. W. Gilmore and his assistant John Floyd Strayer and was named and shortly described by Gilmore one year later. The generic name is derived from Greek: βραχύς, brachys, "short", Greek: κέρας, keras, "horn" and Greek: ὤψ, ops, "face", in reference to the short snout. The specific name refers to the provenance from Montana.
All that was found were incomplete and jumbled remains of five juvenile individuals of about 1.5 m (5 feet) in length. It has been speculated that these juveniles may have been nest mates that stayed together after hatching. The holotype specimen is USNM 7951, a partial skull. The paratypes are USNM 7952, a snout, USNM 7953, a partial skeleton with skull and USNM 7957, a foot.
This brief starts where responsible research should: with the source description of “Brachyceratops” as dubious genus of reptiles (fossil). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as dubious genus of reptiles (fossil). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 29, 2025. The linked authority identifier is Q131602. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1913.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
