Harpymimus
Harpymimus okladnikovi
The catalogue presents Harpymimus as a omnivore member of Deinocheiridae that lived during the Cretaceous, between 113.0–100.0 Ma. Its estimated range is 2.0–3.0 m in length and 50–80 kg in mass, giving a practical sense of scale. Reference material comes from Shinekhudag Formation, Mongolia. Size and mass are approximations and may change with new fossils or methods.
