Rare, 4.8" Fossil Fish (Amphiplaga) - Wyoming
This is a very nice, 4.8" long fossil fish (Amphiplaga brachyptera) from the Green River Formation of Wyoming. It is an uncommon fish making up less than 1% of the total fossil fish collected. It is typically quite small and it close to 5 inches in length this one is huge for the species. Not only in it large, but it is very nicely preserved and presented on a thick slab of shale. This specimen includes an acrylic display stand.
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.
