13+" Unprepared Mioplosus with Diplomystus - Green River Formation

This is an unprepared fish plate with a large, 13-15" long Mioplosus labracoides and a smaller Diplomystus dentatus. It comes from the Gastropod Layer of the Green River Formation.

While the fish does appear to be complete and articulated, as with all unprepared fossils there are no guarantees. You don't know what will be under the surface.
