Insect Fossil
Insect Fossils are relatively rare. There are not many places in the world where fossilization can take place to preserve the delicate exoskeletons. The Green River formation found in Colorado, Utah, and Wyoming is one of those places. These insect fossils came from Wyoming and are from the Eocene Epoch.

In addition to Green river fossil insects, The Solnhofen Limestone in Germany is another place where insect fossils are found. The Solnhofen fossils are Jurassic age.
Many insect fossils come from amber.
