Is this a trilobite head?

Found this near Utica, is it a trilobite head? The area has tons of triarthrus heads and nautiloids, but nothing as big as this. Unfortunately this is the best photo I can get at the moment as I stupidly misplaced the possible head. Also included is a fossilized sea shell, if anyone knows what species it belongs to that'd be great.

It certainly looks like it could be partial trilobite, but it would be better to see it without the mud, and with a proper scale, to offer a better ID.  Hopefully you can re-find it.
