50 million years ago, Wyoming's Green River Formation was comprised of 25,000 square miles (40,000 km) of interconnected subtropical lakes. Today the area is known as the "Fossil Lake", boasting some of the most abundant and well-preserved freshwater fossils anywhere in the world.

Highlights of this three panel fossil mural include the large surface-feeder, Diplomystus dentatus, characterized by its distinctive upturned mouth bristling with teeth, and Knightia eocaena, an extinct relative of today's herring and sardines. Also featured is the temperate bass, Cockerellites liops, and the pointed-teeth, predatory percid, Mioplosus labracoides.

This fish quartet—nestled together on a natural rock matrix triptych—capture a beautiful snapshot of an ancient American ecosystem.
