About Zavacephale
Zavacephale (meaning "origin head") is an extinct genus of pachycephalosaurian dinosaurs known from the Early Cretaceous Khuren Dukh Formation of Mongolia. The genus contains a single species, Zavacephale rinpoche, known from a partial articulated skeleton including a nearly complete skull. It is both the oldest definitive pachycephalosaur known, as well as the most complete. Its skull bears a well-developed dome structure, as seen in most members of the clade.
