2018 marks the 25th anniversary of the discovery of the painted bison skull at the Cooper site in Harper County, Oklahoma. The skull, which is over 10,000 years old, remains the earliest painted object ever found in the Americas. In this public lecture, Dr. Leland Bement, the archaeologist who led the excavations at Cooper, describes the discovery itself and details what we have learned about Paleoindian bison hunting in the 25 years since it was found. After the lecture, the Oklahoma Archeological Survey will host a reception for all attendees.
