Cretaceous
Anchiceratops
Anchiceratops ornatus
The catalogue presents Anchiceratops as a herbivore member of Ceratopsidae that lived during the Cretaceous, between 73.0–70.0 Ma. Its estimated range is 5.0–6.0 m in length and 1.0–2.0 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.
