In Depth

       The first pachycepahlosaurid dinosaur known from Alaska,‭ ‬Alaskacephale is also one of the few dinosaurs known to have lived in the area that would become that state.‭ ‬Unfortunately not a lot is known about this dinosaur because of a current sever lack of remains,‭ ‬but the original describers believe that Alaskacephale may have been roughly the same size as the better preserved Prenocephale.

       The holotype specimen of Alaskacephale was first described by Gangloff,‭ ‬Fiorillo and Norton in‭ ‬2005,‭ ‬but it was not established as a genus until it was re-described by Sullivan in‭ ‬2006.‭ ‬The genus name is in reference to the state of Alaska and the fact that it is a pachycephalosaurid dinosaur.‭ ‬The type species name is in honour of R.‭ ‬A.‭ ‬Gangloffi,‭ ‬one of the original describers.
