Fossil Butte National Monument

Some of the world's best preserved fossils are found in the flat-topped ridges of southwestern Wyoming's cold sagebrush desert. Fossilized fish, insects, plants, reptiles, birds, and mammals are exceptional for their abundance, variety, and detail of preservation.  Most remarkable is the story they tell of ancient life in a sub-tropical landscape.
