Cretaceous
Saurolophus
Saurolophus osborni
The catalogue presents Saurolophus as a herbivore member of Hadrosauridae that lived during the Cretaceous, between 70.0–68.0 Ma. Its estimated range is 9.0–13.0 m in length and 2.0–4.0 t in mass, giving a practical sense of scale. Reference material comes from Horseshoe Canyon Formation, Alberta, Canada. Size and mass are approximations and may change with new fossils or methods.
