However, the holotype from Khulsan has primitive premaxillary teeth, a feature inconsistent with the derived morphology of Bagaceratops. Most of these referred specimens have been re-identified as belonging to Bagaceratops, and Breviceratops is now restricted to the holotype, ZPAL MgD-I/116.
The holotype from Khulsan has primitive premaxillary teeth, which contradicts the typical morphology found in Bagaceratops. Most of the specimens previously identified as belonging to a different species have been reclassified as Bagaceratops. The Breviceratops name is now limited to the holotype, ZPAL MgD-I/116.
