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?
