RE: Pterosaur diversity (was: Re: Waimanu)

Hi Nick, In regard to the root opsi/ ops, is this
where we get the derived meaning for "eye" in medicine
and in some(possibly incorrect)paleontological
nomenclature?. If I remember correctly, the amphibian
name Eryops in the past has always translated as
"drawn-out eye", when according to what you've stated
it should be "drawn-out face".  --Mark Hallett
