Cretaceous
Neuquensaurus
Neuquensaurus australis
The catalogue presents Neuquensaurus as a herbivore member of Saltasauridae that lived during the Cretaceous, between 83.0–70.0 Ma. Its estimated range is 7.0–8.0 m in length and 4.5–5.0 t in mass, giving a practical sense of scale. Reference material comes from Anacleto Formation, Neuquén, Argentina. Size and mass are approximations and may change with new fossils or methods.
