Skeletal reconstruction of the Late Cretaceous protoceratopsid Bagaceratops rozhdestvenskyi. Skull (predominantly) based on specimens IVPP V12513, PIN 3142/4, and PIN 3142/5;[1] and skeleton based on KID 196 and MPC-D 100/535.[2][3] Since the skeleton of Bagaceratops was very similar to that of Protoceratops, some elements have been referenced.[4] References ↑ (2019).
