USGS shows Upper Ordovician Maquoketa Formation in Lincoln County.  Looks like a good match for the asaphid trilobite: Anataphrus sp.

Trilobites are laterally symmetrical. Blastoids are radially symmetrical. I'm seeing radial symmetry. I'm in the blastoid camp.

Fossil hunting is easy -- they don't run away when you shoot at them!
