Rare, 2.1" Fossil Crayfish (Procambarus) - Green River Formation

Rare, Fossil Crayfish (Procambarus) - Green River Formation #198048

This is an extremely rare, well preserved 2.1" fossil crayfish (Procambarus) from the Green River Formation, Kemmerer, Wyoming. This beautiful specimen shows many fine details of the crayfish's appendages, antennae and two claws. These crayfish don't come along often and the opportunity to purchase one shouldn't be passed up.

Comes with an acrylic 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.
