Yangchuanosaurus shangyouensis
The catalogue presents Yangchuanosaurus as a carnivore member of Metriacanthosauridae that lived during the Jurassic, between 163.5–157.3 Ma. Its estimated range is 8.0–10.5 m in length and 2.0–3.0 t in mass, giving a practical sense of scale. Reference material comes from Shangshaximiao Formation, Sichuan, China. Size and mass are approximations and may change with new fossils or methods.
