摘要：
Archeological excavations at Murray Springs, Cochise County, Arizona, in July 1967 uncovered a unique bone tool in the Clovis occupation level and in association with bones of a mammoth. The tool may be a wrench for straightening shafts of spears; if so, shaft diameters ranging from 14 to 17 millimeters were most likely used in hafting Clovis projectile points.
