Jurassic
Spinophorosaurus
Spinophorosaurus nigerensis
The catalogue presents Spinophorosaurus as a herbivore member of Spinophorosauridae that lived during the Jurassic, between 170.9–165.3 Ma. Its estimated range is 13.0 m in length and 7 t in mass, giving a practical sense of scale. Reference material comes from Basal Irhazer Group near Aderbissinat, Agadez Region, Niger. Size and mass are approximations and may change with new fossils or methods.
