Notes

Stegoceras had a thick-domed skull typical of pachycephalosaurs. It is generally thought their skulls were for head-butting others of the same species. Stress simulations indicate the skulls and rigid spinal columns could absorb high impact. However, some scientists think the skulls were more suited for display or 'pushing' rather than actual head-butting.
