specimen comes from the "18 inch layer" in the Green River Formation which produces darker colored and often more detailed fish fossils than the split fish layers. Fossils fish in these layers typically split out totally under the surface of the rock, and can only be identified by looking for the raised bumps of their back bone. Preparing a fish like this would have taken many hours of detailed work using hand tools.

If you look closely you can see how Phareodus has a mouthful of sharp pointy teeth making is a voracious lake predator. In fact the name Phareodus actually means "to have tooth" Spines from other fish such as Mioplosus and Priscacara have frequently been found preserved in it's stomach.
