Trike fights

Whew, finally caught up on the Digests.  This will be a little late,
but:

Scott Sampson (of Einiosaurus fame) postulated a head-wrestling or
shoving strategy for Triceratops bulls, with an illustration showing
the brow horns "locked" together and nose horns about at the level of
the jugal (cheek) prongs.  Looked like the next step would be for each
wrestler to try to hook his nose horn under the opponent's jugal to
get an overwhelming advantage.  The illustration works nicely, if one
accepts the theory that the morphs with the nearly-vertical brow horns
are males.  Not sure how the females would wrestle; the bovine analogy
suggests they likely would have dominance hierarchies of their own,
but after all, who knows?  (The "I can't explain it so I'll insist on
its hypotheticism" defence)

Thanks to the fellow with the New Book on Functional Morphology for
starting this thread, with more high-quality ceratop(s)ian content
than the list has had recently, or perhaps ever.  And thanks also to
the other contributors for making it so.
