10" Impressive Fish Fossil (Phareodus) - Wyoming

This is a beautifully preserved, 10" long fossil fish (Phareodus) from the Green River Formation of Wyoming. It was collected from the famous "18 inch layer" at the Lindgren Quarry near Kemmerer, Wyoming. The fish has a reddish brown coloration to it and the level of preservation is excellent. Just check out the pectoral fins!

It is nicely presented on a thin 15 x 9.2" slab of shale. We can add a backing and wall mounting hardware 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.
