Cretaceous
Nigersaurus
Nigersaurus taqueti
The catalogue presents Nigersaurus as a herbivore member of Rebbachisauridae that lived during the Cretaceous, between 115.0–105.0 Ma. Its estimated range is 9.0 m in length and 1.9–4.0 t in mass, giving a practical sense of scale. Reference material comes from Elrhaz Formation, Niger. Size and mass are approximations and may change with new fossils or methods.
