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
