Prenocephale is a genus of pachycephalosaurid dinosaur from the Late Cretaceous of Mongolia. However, it lived in the dry, upland forests, far away from the deserts that make Mongolia famous. It, along with Pachycephalosaurus, is one of the largest species of pachycephalosaur. They have a thick domed skull, which was used for ramming each other on the flanks during fights between males and as a defense.
In The Land Before Time
Two Prenocephale 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.
