5" Long, Unprepared Fossil Fish - Wyoming

This is an unprepared fish plate that likely contains a Knightia eocaena or Diplomystus dentatus, collected from the Green River Formation near Kemmerer, Wyoming. It appears to be around 5" in length and is on a 7.6 x 5.5" slab of rock.

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.
