Cretaceous
Argentinosaurus
Argentinosaurus huinculensis
The catalogue presents Argentinosaurus as a herbivore member of Titanosauridae that lived during the Cretaceous, between 100.5–94.0 Ma. Its estimated range is 30.0–35.0 m in length and 60.0–90.0 t in mass, giving a practical sense of scale. Reference material comes from Huincul Formation, Argentina. Size and mass are approximations and may change with new fossils or methods.
