Abstract
The Lehner site fauna includes at least nine individuals of Mammuthus columbi and one each of Equus, Bison, and Tapirus. Mammoth material consists chiefly of jaws and teeth and shows a great range of individual variation. The tapir is represented by one of the largest fossil tapir jaws described from North America. The accumulation is considered to represent several kills over a period of several months. Climate at the time of the Lehner hunts was probably more humid than at present, but not tropical. The radiocarbon date of about 11,000 B.P. is considered reasonable. New genera reported from other early man faunas are Neotoma from the Ventana complex and Bison from the Naco site.
