英文摘要	Here we describe a postcranial skeleton of Bagaceratops (Ceratopsia) which was found in the Baruungoyot Formation (Upper Cretaceous) in Hermiin Tsav of southwestern Gobi Desert, Mongolia in 2007. It is important in terms of the first report on the postcranial skeleton of Bagaceratops. Although the cranial differences stand out between Bagaceratops and its sister taxon Protoceratops, two genera are very similar to each other in the postcranial skeleton except for the shape and position of clavicles. Their similarity appears in the number and shape of a sacrum, tall neural spines of caudals, the presence of clavicles, a flat scapular blade almost perpendicular to glenoid, coracoids with a smooth and arcuate anterior portion, a small olecranon process, manus much smaller than pes, a large and pendant femoral fourth trochanter, and the tibia longer than the femur. While short and rod-like clavicles of Protoceratops are articulated with both scapula and coracoid, however, they are curved distally in front of the coracoid in Bagaceratops. Bagaceratops with a laterally flat and high tail like Protoceratops mainly lived in interdune ponds and other freshwater wetlands, and the high neural spines of the caudal vertebrate of protoceratopsids may be an adaptative feature for living in aquatic environments.
