  Speaking of cassowaries, it has recently come to my attention that
cassowaries do have a bony core to their casque, though not as
prominent as the casque itself, and I am unaware that when the casque
breaks if the bone is unaffected.

  This goes back to a post I made long ago when I didn't know whether
cassowaries had bony casque cores like oviraptor crests.
