THIS IS NOT A CLOVIS TECHNOLOGY! The bottom specimen is related to Lerma/El Jobo([url]http://radiocarbon.library.arizona.edu/radiocarbon/GetFileServlet?file=file:///data1/pdf/Radiocarbon/Volume42/Number2/azu_radiocarbon_v42_n2_305_310_v.pdf&type=application/pdflanceolate [/url]) projectile points (dating to perhaps ~ 16,000 BP-(14th millennium BC in the New World), and represent a common bifacial style found, in lithic assemblages of cultures possessing bifacial technology, throughout the world during the Upper Paleolithic. it is probably a product of convergent evolution, developed autochthonously, in Asia, as well as in Europe and in North America; this pattern can be hypothesized to have been a continuation, in some Old World cultures, of Acheulian bifacial handaxe technology,very visible in eroded channels incising river valleys deeply during the Pleistocene, to upper PAleolithic Solutrean (~21,000 - 16,000 BP)hunters in France, although no connection to Solutrian technology is proposed here. The basal fragment is similar to Mesa projectiles from Alaska, or Agate BAsin ([url]http://mapserver.museum.state.il.us/faunmapweb/oneanalysisunit.php?siteID=175&unitID=Agate%20Basin%20Component [/url]) projectiles (which may have evolved from Mesa[~14,000 BP] hunting technology), from the North American Plains, and date from >12,000BP.
