Lorenzo and Mirambell (199) recently concluded that "these dates provide clear evidence of human activity at the site about 22,000 years ago." At the site a prismatic obsidian blade found under a tree trunk dated to 23,950 950 years B. was obsidian hydration dated to between 21,250 and 25,000 years B. P., a circular scraper manufactured from microcrystalline quartz by direct percussion (Lorenzo and Mirambell 191).At Tlapacoya, Mexico, presumed hearths associated with animal bone middens were dated to 24,000 4000 and 21,700 500 years B.
