Tapuiasaurus macedoi
The catalogue presents Tapuiasaurus as a herbivore member of Titanosauridae that lived during the Cretaceous, between 130.0–120.0 Ma. Its estimated range is 12.0–13.0 m in length and 6.0–8.0 t in mass, giving a practical sense of scale. Reference material comes from Quiricó Formation, Minas Gerais, Brasil. Size and mass are approximations and may change with new fossils or methods.
