MASS MORTALITY OF FOSSIL FISH

52 million years old

Green River Shales, Wyoming, USA
 
Along the Green River in Wyoming, beautifully preserved fossil fish are found in layers of fine-grained limestone. It was formed at the bottom of a lake that existed in the Eocene period, when this part of the U.S.A. had a wet, tropical climate.

This slab is from the base of the ’18 inch layer’ on Fossil Butte in western Wyoming, which has a density of several hundred fish per square metre. This mass mortality was probably due to a change in temperature or water chemistry.
