Breviceratops (Kurzanov,1990)
> B.kozlowskii
(Maryanska
& Osmolska,1975) =
Protoceratops
kozlowskii ? (Maryanska
& Osmolska,1975)
Protoceratops
(and Breviceratops) retain premaxillary teeth all other
neoceratopians have lost them. B.kozlowskii
has a short and narrow snout, a large, deep antorbital fossa, and a
short, flattened nasal horn.
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
