FOSSIL INSECTS 

52 million years old


Green River Shales, Wyoming, U.S.A.
 

 Along the present-day Green River in Colorado, Wyoming, and Utah, beautifully preserved fossils are found in a layer of fine-grained shales and limestones. They were preserved 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.

​​​​​​​
These insects are known as March flies (Plecia pealei) and are the most common insects found in these rocks. This family of flies extends back as far as the Cretaceous period, which indicates that they may have co-evolved with flowering plants. 
 

This is a very good example of fossil insects. There has been no retouching or restoration.
