Futalognkosaurus
Futalognkosaurus dukei
The catalogue presents Futalognkosaurus as a herbivore member of Titanosauridae that lived during the Cretaceous, between 87.0–85.0 Ma. Its estimated range is 26.0–32.0 m in length and 50.0–70.0 t in mass, giving a practical sense of scale. Reference material comes from Portezuelo Formation, Neuquén, Argentina. Size and mass are approximations and may change with new fossils or methods.
