.25" Fossil Insect - Green River Formation, Colorado

This is a .25" wide insect collected from the Green River Formation of Piceance Creek Basin, Colorado. While this formation is best known for well preserved fossil fish found in Wyoming, other sections of the formation contain a very diverse flora and insect fauna.

This plate comes with an acrylic display stand.

50 million years ago, in the Eocene, 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.
