Cretaceous
Erlikosaurus
Erlikosaurus andrewsi
The catalogue presents Erlikosaurus as a herbivore member of Therizinosauridae that lived during the Cretaceous, between 93.9–90.0 Ma. Its estimated range is 4.5–6.0 m in length and 150–200 kg in mass, giving a practical sense of scale. Reference material comes from Bayan Shireh Formation, Mongolia. Size and mass are approximations and may change with new fossils or methods.
