Fossil Fishing in Southwestern Wyoming

Go fishing for fossils in Wyoming's 52-million-year-old "Fossil Lake" with curator Dr. Lance Grande and his team, and you'll come home with quite a catch. Over the last 20 years, Dr. Grande has collected thousands of fossilized fish, as well as plants, insects, crocodiles, turtles, stingrays, birds, mammals, and more, from the Green River Formation—the world's most productive freshwater fossil deposit!
