Alioramus
Alioramus remotus
The catalogue presents Alioramus as a carnivore member of Tyrannosauridae that lived during the Cretaceous, between 70.0–66.0 Ma. Its estimated range is 5.0–6.0 m in length and 700–1000 kg in mass, giving a practical sense of scale. Reference material comes from Nogoon Tsav, Mongolia. Size and mass are approximations and may change with new fossils or methods.
