Cretaceous
Tarbosaurus
Tarbosaurus bataar
The catalogue presents Tarbosaurus as a carnivore member of Tyrannosauridae that lived during the Cretaceous, between 70.0–66.0 Ma. Its estimated range is 10.0–12.0 m in length and 4.0–5.0 t in mass, giving a practical sense of scale. Reference material comes from Nemegt Formation, Mongolia. Size and mass are approximations and may change with new fossils or methods.
