Homalocephale (ho-mah-low-SEF-uh-lee)
A Late Cretaceous pachycephalosaur from Mongolia [Greek homalos, "level" + kephale, "head"]. Homalocephale had a flat head. The rough skull was patterned with small cavities and bone-bumps. The shape of the hipbones shows that the 'bone-heads' could have given birth to live babies instead of laying eggs.
