Isn't "Xuanhuasaurus" a member of the ever-mysterious group of ?basal
marginocephalians the Chaoyoungosauridae? I haven't seen them mentioned
in anything recent, including _The Dinosauria_ and I'm curious as to what
their current status is. Are they still awaiting description,
non-dinosaurian, or what??
