Nipponosaurus
Nipponosaurus sachalinensis
The catalogue presents Nipponosaurus as a herbivore member of Lambeosaurinae that lived during the Cretaceous, between 85.7–83.6 Ma. Its estimated range is 4.0–5.0 m in length and 300–500 kg in mass, giving a practical sense of scale. Reference material comes from Hakobuchi Formation, Sakhalin, Japan. Size and mass are approximations and may change with new fossils or methods.
