Once again, I am seeking assistance in identifying a Mazon Creek concretion fossil. Might be an easy one for someone here, but I'm just not finding it. Both halves are pictured below. Thanks!

I've tentatively identified a number of Mazon pieces in my possession, and I was wondering if I could get some confirmations or corrections from those of you (all of you) who are more knowledgeable and experienced than I. The first (#1) based on length, fossilization curvature, and the pyritized mouth and throat slit, I believe to be Gilpichthys greenei.
