The visitor center at Fossil Butte National Monument may be small, but it’s jam packed with AMAZING fossils, many excavated here or nearby. Fossil Lake once covered this area and the conditions existing at that time preserved fossil remains especially well. Fossil Butte National Monument is in Kemmerer in southwestern Wyoming.
The fossils were discovered in this area in the mid 1800s. One well-known collector, Lee Craig, quarried and prepared fossils for museums and private collectors from 1897 to 1937. When collectors illegally used bulldozers in fossil beds nearby, preservation became a higher priority. The conservation of this site’s unique treasures was ensured in 1972, when it was established as a national monument.
Fossil Butte fossils
This fossil was huge! It’s from the genus Borelosuchus, neither a true crocodile nor a true alligator. They could grow to a length of 16 feet.
Fish fossils
Here are some of the fish fossils on display. Twenty seven species have been found in this area.
As I mentioned in my Fishing for Fossils post, this is one of the best places in the world to find fossils of fish. Since you cannot collect fossils at the monument, we dug fossils at a commercial business just east of Fossil Butte National Monument.
