10000 year old Bison kill mystery

Members in the NEWS: "Lawrence Todd, a Colorado State University archaeologist, and David Rapson, an Iowa State University archaeologist, were mentioned in the July 4, 2006, Rocky Mountain News (Denver) story 'Tackling 10,000-year-old mystery.' The article detailed research on faunal remains at the Hudson-Meng Bison Kill on the Oglala National Grassland, northeast of Denver, including investigations into who or what killed the bison. The cause of death has been debated for decades, with some researchers espousing a 'stamped-'em-and-spear-'em' theory that attributes the cause to Paleoindian hunting. Others advocate a natural cause, such as a lightening strike or grass fire-asphyxiation scenario. Among the natural cause theorists are Todd and Rapson, who was quoted about their interpretations in the story. 'We're in kind of a funny situation here. We feel our research has brought into question the original [hunting] interpretation. But if it's natural mortality, we're unable to provide a strong interpretive answer for what did happen. This dispute will go on for years and will be seriously, acrimoniously debated,' he was quoted as saying. The story outlines the site's history and background of both theories."
