12.8" Scarce Fossil Fish (Phareodus) - Wyoming
This is a very nice, 12.8" long fossil fish (Phareodus encaustus) from the Green River Formation of Wyoming. We collected it this past summer from the "gastropod layers" at the Lindgren Quarry outside of Kemmerer, Wyoming. A really nicely preserved specimen with great fin detail and visible teeth in its mouth.
It comes with a display stand or we can add a backing and wall hanger upon request.

Phareodus is a genus of predatory freshwater fish found in the famous Fossil Lake deposits of the Green River Formation in Wyoming. It had a mouthful of sharp pointy teeth, making it a voracious lake predator. In fact, the name Phareodus actually means "to have teeth". Spines from other fish such as Mioplosus and Priscacara have frequently been found preserved in their stomachs.
About Fossil Lake
50 million years ago, in the Eocene epoch, these fish thrived in Fossil Lake, which was fed by the Uinta and Rocky Mountain highlands. The anoxic conditions at the bottom of Fossil Lake slowed bacterial decomposition, prevented scavengers from disturbing corpses, and, most interestingly, suffocated creatures that ventured into the oxygen-starved aquatic layer. The result is a miraculous exhibition of Eocene biota: a subtropical aquatic community within sycamore forests, teeming with creatures such as freshwater stingrays, dog-sized horses, menacing alligators, early flying bats, and one of the first primates.
