||Anaxial's Annex. Two-legged, herbivorous dinosaurs, boneheads are named for their tremendously thick, domed, skulls. They live in small herds of a dozen or so adults, and are rather more intelligent than they at first appear. The females lay their eggs in nests which they protect until the young hatch and join the herd. They are greenish in colour with black mottled patches and a pale grey forehead. Male boneheads challenge each other for access to breeding females by charging at each other and whacking their heads together until one submits. Against predators or other threats, they can use a similar tactic, although opponents of human size or smaller are difficult to hit in this manner, and will likely simply be kicked instead.
