Bagaceratops
Bagaceratops rozhdestvenskyi
The catalogue presents Bagaceratops as a herbivore member of Protoceratopsidae that lived during the Cretaceous, between 80.0–72.0 Ma. Its estimated range is 1.0 m in length and 15–22 kg in mass, giving a practical sense of scale. Reference material comes from Barun Goyot Formation, Mongolia. Size and mass are approximations and may change with new fossils or methods.
