Geological and Geochemical Evidence Concerning the Antiquity of Bone Tools from Tule Springs, Site 2, Clark County, Nevada
Two bone objects from the Tule Springs site, possibly tools, occurred in ancient sedimentary fill of a small spring outlet-channel remnant. The ancient spring was active more than 40,000 years ago and again 12,000 to 13,000 years ago. The fill and the bone contained therein could be of either age. Chemical and X-ray analysis on bone of the known ages and bone from the fill showed no significant or systematic differences in fluorine, uranium, nitr…
