Description

The Prenocephale similar to others of its kind is only known from its skull. The skull was very thick allowing it to fossilize very well whereas the rest of its body might not have done so well. It was very similar to the Homalocephale which might actually be a juvenile version of the Prenocephale. If it was the same as the Homalocephale it would have also lived in what is now North America instead of just Mongolia. Its head was rounded and sloped, unlike the flat wedge shape of the Homalocephale. Evidence has shown that the Prenocephale and others of its family may have started out with a flat head while slowly developing the domed slope. It had a row of spikes and bumps around the edge of the dome. It was probably similar to others of the same family with a short strong neck, strong legs, and small arms. Although it is not altogether clear what it ate, it probably was an omnivore eating both plant live and animal life, like insects.
