Superb 18 Inch Layer Priscacara and Dyplomystus

This is a beautiful plate from the famous Green River Formation with a Cockerellites liops and Diplomystus dentatus entombed right next to each other. The detailed Priscacara is 4 inches long and shows all of the incredible details of this elegant fossil perch. The Diplomystus is just under 5 inches long and similarly detailed. Both fish are centered on a nice large slab of shale which can be cut down to different sizes or shapes based at the buyers request.

These fish come 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 back bone create. They then cut these fish out and take them to a lab where the fish which maybe up to an inch under the surface of the rock are meticulously extracted under microscope with hand tools.

Like essentially ALL fish from the 18 inch layer, there is some minor restoration to repair small bits of scale that flaked off during prep and on some fin tips (which typically don't preserve well)
