15.4" Detailed Fossil Branch - Wyoming
This is a detailed 15.4" long fossil branch from the Green River Formation of Wyoming. It was collected from Hay Hollow Quarry. This specimen shows excellent preservation: the lack of budding structures along its length may indicate that this branch fell in late fall or winter. The shale measures 14.75 x 9.4", and is accompanied by an acrylic-metal 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.
