This is a spectacular fossil fish "mural" from the Green River Formation of Wyoming. It measures 42" tall by 34" wide. There is a partial fossil palm frond on the lower corner of the plate as well as beautifully preserved Phareodus and Mioplosus.
The fish fossils have been inlaid into the rock for display purposes, while the palm frond is in its natural position. The entire piece has been backed for stability and well mounting hardware is installed allowing the piece to be easily hung on a wall.
It comes from the coveted 18 inch layer of the Green River Formation which produces darker and more detailed fish than the majority on the market. The rock from this layer is much harder and more durable. This layer is typically collected at night using low-angle light to see the bump in the rock that the backbone creates. They then cut these fish out and take them to a lab where the fish, which may be up to an inch under the surface of the rock, are meticulously extracted under microscope with hand tools.
50 million years ago, in the Eocene these fish thrived in Fossil Lake fed by 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 in 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.
