Borealopelta
Borealopelta markmitchelli
The catalogue presents Borealopelta as a herbivore member of Nodosauridae that lived during the Cretaceous, between 112.0–110.0 Ma. Its estimated range is 5.5 m in length and 1.3–1.5 t in mass, giving a practical sense of scale. Reference material comes from Clearwater Formation, Alberta, Canada. Size and mass are approximations and may change with new fossils or methods.
