Robert L. Kelly began collecting arrowheads in farmers� fields when he was 10 years old. He has participated in archaeological research since 1973, when he was a sophomore in high school.

He currently is conducting research into the archaeology of Wyoming�s Bighorn and Absaroka Mountains, and Glacier National Park. A former president of the Society for American Archaeology and current editor of American Antiquity, Kelly has published over 100 articles and books, including The Foraging Spectrum: Diversity in Hunting and Gathering Societies (1995) and The Lifeways of Hunter-Gatherers (2013). Dr. Kelly has been a professor at the University of Wyoming since 1997. David Hurst Thomas has served as curator of anthropology at the American Museum of Natural History in New York City since 1972. A specialist in Native American archaeology, Thomas discovered both Gatecliff Shelter (Nevada) and the lost 16th- and 17th-century Franciscan mission Santa Catalina de Guale on St. Catherine�s Island, Georgia. He has led the long-term excavation of Mission San Marcos near Santa Fe (New Mexico) and recently returned to St. Catherine�s Island for long-term archaeological exploration. A founding trustee of the National Museum of the American Indian at the Smithsonian since 1989, Thomas has published extensively. His works include 100 papers and 30 books -- most recently, the bestselling Skull Wars: Kennewick Man, Archaeology, and The Battle for Native American Identity. Archaeologist Thomas likes "old stuff," including his 1961 Corvette, his 130-year-old house, and the Oakland Raiders.
