Alaskacephale

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".
