I found myself hearing Michael Ryan say “I remember every dinosaur jaw bone I’ve ever seen, Mr. Potter.” And the sign out front reads “Ryan’s Dinosaur bits – since 347 BC”. The effect is magic.

Any life reconstruction is going to involve speculation, especially when so little material is known.
I suppose one could argue that a jawbone is too little material to do a reconstruction at all, but in this case it is unlikely that better material will be found any time soon so any future reconstruction will most likely involve equal amounts of speculation.

I find the colorful illustration beautiful but entirely too speculative. Basal neoceratopsids exhibited a wide range of morphologies. I mean, look at the difference between, say, Cerasinops or Archaeoceratops and Udanoceratops. These two new guys are each known from a jaw fragment!

This illustration is jumping the gun a bit, I’m afraid.
