Camarasaurus
Camarasaurus supremus
The catalogue presents Camarasaurus as a herbivore member of Camarasauridae that lived during the Jurassic, between 156.3–145.0 Ma. Its estimated range is 15.0–18.0 m in length and 15.0–25.0 t in mass, giving a practical sense of scale. Reference material comes from Morrison Formation, Colorado, USA. Size and mass are approximations and may change with new fossils or methods.
