14" Fossil Fish (Phareodus) - Uncommon Species
This is a large, 13" long Phareodus fossil fish from the Green River Formation of Wyoming. It's wonderfully detailed and nicely presented on a 19 x 13" slab of shale which has been backed for stability. This specimen includes a display stand or we can add a backing and wall hanger upon request.
Phareodus had a mouthful of sharp pointy teeth making it 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 their stomachs.
50 million years ago, in the Eocene, these fish thrived in Fossil Lake, which was fed by 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 in 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.
