In Depth

       The annoying thing about Amtocephale is that it is yet another pachycephalosaur genus that is known only from skull material,‭ ‬specifically the thick dome.‭ ‬The exciting thing about Amtocephale however is that at the time of its discovery it represents what might be the oldest known pachycephalosaur genus.
