8.3" Phareodus Fish Fossil - 18 Inch Layer

This is a large 8.3" example of one of the more uncommon fossil fish found in the Green River Formation. It is a Phareodus testis and it was found in the 18 inch layer which produces darker and more detailed fossil fish. It's nicely centered on a 12.5x8.2" piece of rock. There is one repaired crack in the rock, but it is barely noticeable and does not go through the fish.

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.
