Stegoceras validum

Stegoceras is a genus of pachycephalosaurid dinosaur from the Late Cretaceous of North America. It is one of the smallest known pachycephalosaurs and it is also one of the first of the group known. It is also one of the most completely known pachycephalosaurs, as it is known from skeletons, skulls, and skull domes. A study was carried out on its dome and found out that, unlike those of other pachycephalosaurs, the dome of Stegoceras could withstand really high pressure. Because of this, it is theorized that it was capable of butting heads with rivals, something that many other species couldn't do without snapping their necks.

Two Stegoceras in the TV series.

Two Stegoceras appear twice in The Land Before Time TV series. In The Cave of Many Voices, they steal some tree stars from Ducky but abandon them when Ruby chases them away. In The Great Log Running Game, they are seen eating some tree sweets, before Cera chases them away during the song I Feel Mad.
