Cretaceous
Styracosaurus
Styracosaurus albertensis
The catalogue presents Styracosaurus as a herbivore member of Ceratopsidae that lived during the Cretaceous, between 75.5–74.5 Ma. Its estimated range is 5.0–5.5 m in length and 1.8–2.7 t in mass, giving a practical sense of scale. Reference material comes from Dinosaur Park Formation, Alberta, Canada. Size and mass are approximations and may change with new fossils or methods.
