Alaskacephale is a pachycephalosaurid dinosaur that lived in the Late Cretaceous (around 80 to 69 million years ago).
Alaskacephale was named by Robert Sullivan in 2006. Alaskacephale was about half the size of Pachycephalosaurus wyomingensis and three quarters the size of Prenocephale, and about the same size as "Prenocephale" edmontonensis and Foraminacephale.
