Unknown Fish Fossil

[Shuko]

I bought this fossil at the Science Museum of Minnesota, and the label simply stated that it was a "fossil fish." It cost me $14.95, and the stone appears to be a kind of limestone, with extremely thin, easily recognizable layers parallel to the surface of the piece. Although the picture doesn't show it, the limestone is a yellowish beige color.

The fish is approx. 4" in length. Any help on identification? Sorry for the lack of detail. ^^;

Here is some detailed info on the Green River formation in Wyoming.

yep it is a Knightia eoceana. from the Green river formation in Kemmerer Wyoming. most likely from the split fish layers of the GRF. Eocene.
