11.8" Fossil Fish (Phareodus) - Wyoming

Fossil Fish (Phareodus) - Wyoming #207902

This is a 11.8" long fossil fish (Phareodus), one of the more uncommon species from the Green River Formation. It was collected recently from a quarry near Kemmerer, Wyoming. The preservation on the fish is pretty good, and you can even see its mouthful of large teeth. There are several repaired cracks running through the limestone slab and the fish.

Comes with a display stand.

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.

50 million years ago, in the Eocene, 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.
