The Lehner Mammoth-Kill Site is a location in southern Arizona that is significant for its association with evidence that mammoths were killed here by Paleo-Indians 9000 years BCE. In 1952, Ed Lehner discovered extinct mammoth bone fragments on his ranch, at the locality now known as the Lehner Mammoth-Kill Site. He notified the Arizona State Museum, and a summer of heavy rains in 1955 exposed more bones. Excavations took place in 1955-56, and again in 1974-75. In the first season, two Clovis projectile points were found among the ribs of a young mammoth.〔(Lehner Mammoth-Kill Site )〕 Artifacts found during these excavations included thirteen fluted Clovis culture projectile points, butchering tools, chipped stone debris and fire hearth features. Bones of a variety of game—twelve immature mammoths, one horse, one tapir, several bison, one camel, one bear, several rabbits, and a garter snake—were excavated at the Lehner site. The Lehner Mammoth kill and camp site exhibited a number of firsts: It was the first site associated with the Clovis culture to have definable fire hearths. These hearths provided the first radiocarbon dates for the culture (9,000 B.C.). This site was also the first to have butchering tools in direct association with animal remains, and the first Clovis association with small animals, camel, and tapir. In addition to the obvious artifact remains, an inter-disciplinary group of scientists including archaeologists, botanists, geochronologists, geologists, paleontologists, palynologists, and zoologists have studied and interpreted a wide range of data from the site that greatly adds to our understanding of the past. 〔(Bureau of Land Management-Lehner Mammoth Kill Site ).
