This is a very detailed March Fly with “chunky” abdomen. The fly exhibits very fine detail in the wings, legs, and body.

The March Fly is in the order diptera. These are stout bodied flies with large eyes.

Insects are quite rare in the fossil record. They are generally small and easily overlooked during collection. These are small but very detailed.
This is from the Green River Formation of Colorado. The Green River Formation is well known for the diversity of fossilized flora and fauna that has been found. Most notable it is known for the fossil fish – that you may also see for sale in this store – but other forms are found as well. nearly the entire ecosystem is represented in some way in the fossils found here.
