Cretaceous
Ruyangosaurus
Ruyangosaurus giganteus
The catalogue presents Ruyangosaurus as a herbivore member of Titanosauridae that lived during the Cretaceous, between 121.4–121.4 Ma. Its estimated range is 28.0–30.0 m in length and 40.0–60.0 t in mass, giving a practical sense of scale. Reference material comes from Mangchuan Formation, Henan, China. Size and mass are approximations and may change with new fossils or methods.
