Named for its size: probably smaller in size than other protoceratopsids. B. rozhdestvensky has a short snout and frill, an additional antorbital fenstra, and a prominent nasal horn core.

It seems possible that al of the basal ceratopian specimens from the Barun Goyot Fm.  perttain to a single species. The most appropriate name for that taxon is Bagaceratops rozhdestvenskyi. Brevicaratops may be regarded as a junior synonym of Bagaceratops
