Dr. Lance Grande's research covers many aspects of fossil and living fishes, including the early development of North American freshwater fish fauna. Over the last 25 years, Lance has led more than 20 field trips to collect fossils from Fossil Lake, a 52-million-year-old lake bed in Wyoming. Thanks to his efforts, The Field Museum currently boasts the world's largest and most extensive fossil collection from the Green River Formation.
