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.

About The 18 Inch Layer Of Fossil Lake

Specimens of this quality come from the coveted 18-inch layer of the Green River Formation, a horizon renowned for producing exceptionally dark, detailed, and well-preserved fossil fish. The limestone from this layer is significantly harder and more durable than that found in many other parts of the formation, likely a result of the deep-water conditions under which it was originally deposited.

These conditions helped preserve fish in remarkable completeness, allowing exceptional specimens to be recovered largely intact. Locating them is a specialized process. The layer is often worked at night using low-angle lighting, which reveals the subtle raised contours created by a fossil fish—particularly the backbone—hidden beneath the surface of the limestone.

Once identified, the surrounding rock is carefully cut away and the specimen is transported to a preparation laboratory. Because the fossil may lie as much as an inch beneath the surface, exposing it requires painstaking work under magnification. Skilled preparators use fine hand tools to gradually remove the overlying limestone, revealing the fossil in extraordinary detail while preserving the delicate bones beneath.
