Well, most crested hadrosaurs had *hollow* crests, so banging
them together would have been rather damaging.  (Lambeosaurus
is a hollow-crested hadrosaur).

Now, the "bne-heads" themselves, the pachycphalosaurs, almost
certainly *did* butt one another like goats.

Extremely unlikely - those claws were far too dangerous for
intraspecific combat use.

Though probably more in the form of "wrestling" matches than
gouging matches.
