Limaysaurus
Limaysaurus tessonei
The catalogue presents Limaysaurus as a herbivore member of Rebbachisauridae that lived during the Cretaceous, between 99.6–97.0 Ma. Its estimated range is 15.0 m in length and 7.0–8.0 t in mass, giving a practical sense of scale. Reference material comes from Lohan Cura Formation, Neuquén, Argentina. Size and mass are approximations and may change with new fossils or methods.
