What can an ancient bison skull tell us about human history? In this episode we talk with Dr. Leland Bement, an archaeologist from the Oklahoma Archaeological Survey who helped in discovering the oldest intentionally painted artefact ever found in the US. Using techniques that included standard archaeological practices as well as interdisciplinary collaborations, Bement’s team was not only able to figure out the story of the Cooper Bison Skull, but they also got a window into the past to learn more about the Folsom people who painted it.
