Notocolossus
Notocolossus gonzalezparejasi
The catalogue presents Notocolossus as a herbivore member of Titanosauria that lived during the Cretaceous, between 89.8–86.3 Ma. Its estimated range is 26.0–28.0 m in length and 60.0–70.0 t in mass, giving a practical sense of scale. Reference material comes from Plottier Formation, Mendoza, Argentina. Size and mass are approximations and may change with new fossils or methods.
