Isisaurus
Isisaurus colberti
The catalogue presents Isisaurus as a herbivore member of Titanosauria that lived during the Cretaceous, between 72.2–66.0 Ma. Its estimated range is 18.0–20.0 m in length and 14.0–18.0 t in mass, giving a practical sense of scale. Reference material comes from Lameta Formation, Maharashtra, India. Size and mass are approximations and may change with new fossils or methods.
