    Green River Formation
    Green River Formation:
    The Green River Formation consists of three very large fossil lakes located in Utah, Colorado and Wyoming.  The smallest of the three lakes is in Wyoming but is by far and away the most productive.  There have been hundreds of different kinds of insects and plants, huge alligators, birds, snakes, and even a couple of small horses recovered from the layers of this formation over the last 100+ years. In addition, the layers are most famous for the hundreds of thousands of fish fossils that have been found that total 14 different varieties of fish.  A quick trip to Fossil Butte National Monument will serve as an excellent introduction to the history and paleontology of the area.
    How Do I Know This is an Authentic Fossil Fish?
    There are several clues that lead us to the conclusion that these are bona fide fossil fish:
    1.  Appearance:
    We hate to state the obvious but take a good look.  It looks like a squished fish.  No real imagination required.  The other bigger clue is that this type of fish is not found alive today.
    2. Collecting Location
    :  These specimens were collected in the Green River Formation of southwestern Wyoming.  It is a rock layer that is famous for being full of fossil fish and other aquatic inhabitants.
    3.  Host Rock:
    The rocks in the Green River Formation, where the fish are found, are sedimentary rocks.  Sedimentary rocks are prime collecting locations for fossils.  If you look in igneous rock  layers (cooled lava) or metamorphic rock layers (squished and heated rock) you are going to have a much harder time finding fossils.
    4.  Associated Fossil
    s:  Again, not to beat a dead horse but, the fish are found in the same area where you can also find aquatic plants, insects common to wetland areas, vertebrates like birds and alligators that live in or near watery areas.  It is not a huge stretch to suggest that where there were fish living and eating and pooping for millions and millions of years that some of those fish might have died, been buried and mineralized.
    5.  Microscopic Study:
    Paleontologists, a scientist who specializes in studying fossils like fossil fish, have examined specimens from the Green River Formation using a microscope. The specimens that are studied have all of the characteristics of aquatic plants and animals and  can be easily distinguished from rocks.
