Fish

The fossil fish from the Green River Fm. near Fossil Butte Monument in Wyoming are among the finest to be found possessing exceptional preservation and quality. There were a series of great inland lakes during the Eocene (50 million years ago) covering SW Wyoming and surrounding areas. The Green River Fm. fish are renowned for their excellent preservation. The lakes were also known for mass mortality sequences in which a large number of fish suddenly die - thought to be caused by toxic algae blooms. These multiple fish "mortality plates" are very unique and quite collectable.
