Pre-Clovis site in Texas?

For decades archaeologists have been searching for sites that conclusively prove that a pre-Clovis culture existed in the Americas.  Several sites have been discovered and excavated within the Western Hemisphere that could potentially be pre-Clovis, but the data is equivocal and has been highly criticized- leaving no sites to date widely accepted as being pre-Clovis.  A recent article published in the March issue of Science (vol. 331) by Michael R. Waters et al, claims to have found proof of a pre-Clovis culture at the Debra L. Friedkin Site in central Texas.  The authors state that a lithic assemblage, dating between 13.2 and 15.5 thousand years ago underlies a Clovis assemblage and that the stratigraphic integrity is sound (Waters et al, 2011).

It will be interesting to see what conclusions further analysis produces about the site, and if it is ultimately accepted by the archaeological community as being pre-Clovis.

As always, please comment and join in the discussion about this site, Waters’ claims, and the dating techniques used.  A full reference to the Science article can be found below.
