Euhelopus

Euhelopus zdanskyi

The catalogue presents Euhelopus as a herbivore member of Camarasauridae that lived during the Cretaceous, between 130.0–113.0 Ma. Its estimated range is 12.0–15.0 m in length and 3.0–5.0 t in mass, giving a practical sense of scale. Reference material comes from Mengyin Formation, Shandong, China. Size and mass are approximations and may change with new fossils or methods.
