The head-butting theory is conventional, but IMHO, not wisdom. :)
Besides the head-butting and somewhat more likely T. rex-butting
ideas, there is one other theory I've seen: In John McLoughlin's book,
_Archosauria_, he suggests that pachycephalosaurs kept their heads
down and the bony dome pointed forward to quickly push tall, thick
vegetation out of its way as it ran. This seems at least somewhat
plausible...at least until our wretched pachyceph ran into a
giant redwood or dosing _Euoplocephalus_ it its path! :)
