Re: Clarifying Hierosaurus sternbergi
since I named Niobrarsaurus, I guess I know the answers.
Niobrarasaurus coleii (Mehl 1936) replaced Heirosaurus coleii Mehl 1936 because
it was near impossible to find anything unique about H. sternbergi Wieland
1909. Since I could not write a diagnosis for it, that made it a nomen dubium
(a "dubius name"). This in turn left H. coleii without a generic name, so
Niobrarasaurus was created.
As for Nodosaurus, Coombs thought H. coleii was synonymous despite the tens of
millions of years separating them. I have shown (with Kirkland) that it is a
valid taxon that can be differentiated from all other ankylosaurs.

if I have this straight...
*Hierosaurus coleii* (Mehl, 1936) = *Niobrarasaurus coleii*
*Hierosaurus sternbergi* (Wieland, 1909) is a nomen dubium. Is it included
*Nodosaurus textilis*? Or is that an old, outmoded idea?
One more question: Several sources said that the reason for the generic
(*Hierosaurus* = "Sacred lizard") is unknown. Anybody have a clue?
