Here is a large plate of the gastropod layer with Knightia eocaena and Diplomystus dentatus. The matrix measures 15x32.75" and the largest fish is 5.75". It is from the Lindgren Quarry near Kemmerer Wyoming. The preservation from this layer is nice and the black fish are very high contrast against the white rock. It has been backed to the highest quality plywood and can be easily hung on the wall using a french cleat. It comes with a custom built wooden foam lined crate for shipping.
