Cretaceous
Spinosaurus
Spinosaurus aegyptiacus
The catalogue presents Spinosaurus as a carnivore member of Spinosauridae that lived during the Cretaceous, between 125.8–83.6 Ma. Its estimated range is 14.0–18.0 m in length and 7.4–20.9 t in mass, giving a practical sense of scale. Reference material comes from Bahariya Formation, Egypt. Size and mass are approximations and may change with new fossils or methods.
