Cretaceous
Wuerhosaurus
Wuerhosaurus homheni
The catalogue presents Wuerhosaurus as a herbivore member of Stegosauridae that lived during the Cretaceous, between 130.0–120.0 Ma. Its estimated range is 6.0–8.0 m in length and 2.0–4.0 t in mass, giving a practical sense of scale. Reference material comes from Tugulu Group, Xinjiang, China. Size and mass are approximations and may change with new fossils or methods.
