If Oviraptor crests were susceptible to breaking off (and then 
growing back) as in cassowarys, would that explain the great variety 
seen in Oviraptor skulls?  It seems likely that if the crest is 
broken, it won't grow back in the right shape.  Of course, it _is_ 
bone, so I don't know if it's possible for it to regrow.  Any ideas?
