any of several ancient North American cultures (Native American) that hunted large herd animals such as mammoth and bison. The archetypal cultures of the Big-Game Hunting Tradition are the Clovis (Clovis complex) and Folsom complexes (Folsom complex), the remains of which have been found throughout North America and date, respectively, to approximately 9,500/9,050–8,850/8,800 BCE and 9,000–8,000 BCE. The tradition ended with the extinction of the Pleistocene megafauna. Although human predation contributed to these extinctions, habitat destruction was the driving force—between about 40,000 and 6,000 years ago, for instance, climate change caused the elimination of an estimated 90 percent of all mammoth habitat in North America. The tradition was followed by the rise of various Archaic cultures (Archaic culture).
