12.8" Scarce Fossil Fish (Phareodus) - Wall Mount

Scarce Fossil Fish (Phareodus) - Wall Mount #300196

This is a 12.8" long fossil fish (Phareodus encaustus) from the Green River Formation of Wyoming. It was collected this past summer outside of Kemmerer, Wyoming. A really nicely preserved specimen with great fin detail and visible teeth in its mouth.

The specimen has a wood backing plate and wall mounting hardware installed, so it is ready to be hung on a wall. There is a repaired crack that runs all the way across the rock/fossil. Spots of gap fill and touchup restoration can be found along this repaired crack.

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 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.
