Maxakalisaurus
Maxakalisaurus topai
The catalogue presents Maxakalisaurus as a herbivore member of Titanosauridae that lived during the Cretaceous, between 80.0–70.0 Ma. Its estimated range is 13.0 m in length and 9.0–10.0 t in mass, giving a practical sense of scale. Reference material comes from Adamantina Formation, Minas Gerais, Brasil. Size and mass are approximations and may change with new fossils or methods.
