9.9" Spectacularly Detailed Fish Fossil (Phareodus) - Wyoming

This is an exquisetly preserved Phareodus fossil fish from our Clear Creek Quarry near Kemmerer, Wyoming. It came out of a rarely collected layer typically referred to as the "Phareodus Layer" which preserves even better detail than the famous 18 inch layer. This layer just produces very few fish which which why it is rarely collected.

The detail on this specimen is spectacular, just check out the awesome fins. It has NO RESTORATION at all. It is located on a thick, 16 x 12.2" slab on limestone which is covered in black dendrites.

About Phareodus

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.
