  • Description: From the Eocene (approx. 50 million years ago), the panel with 5 fossil fish of different species, each in a very good state of preservation and placed on a rectangular cut matrix, framed. This fossil plate gives a wonderful insight into "fossilized ecology".
  • Additional Information: In the Green River Formation of southwestern Wyoming, in the area known as Fossil Lake, two distinct zones of very fine-grained calcareous mud are particularly noted for the preservation of a variety of complete and detailed fossils. These layers represent an Eocene deposit, a rare location where conditions existed for a rich accumulation of undisturbed fossils. The most productive zone, called the fissured fish layer, consists of a series of layered or corrugated limestone muds about 1.8 m (6 ft) thick that contain abundant fish and other fossils. These can be easily split along the layers to reveal the fossils. This thin zone represents approximately 4,000 years of deposition. The second fossil zone, the 18-inch layer, is an unlaminated layer about 46 cm thick that also contains abundantly detailed fossils, but is more difficult to work with because it does not consist of fissile layers.
