If confirmed, the site represents evidence of human settlement in the Americas that pre-dates Clovis culture. Friedkin Paleo-Indian archaeological site in Bell County, Texas has provided archaeological evidence of a human presence in the Americas that pre-dates the Clovis peoples, who until recently were thought to be the first humans to colonize the New World.Until the discovery of the Buttermilk Creek Complex, which appears to have unquestionable evidence of pre-Clovis habitation, there has been a lack of indisputable evidence of pre-Clovis culture in North America.There are several sites in the US with possible pre-Clovis remains including: Although all of these sites have evidence for pre-Clovis occupations, controversy has surrounded some of them or their findings have yet to be thoroughly published, which has kept them from being widely accepted as pre-Clovis sites. Friedkin site multiple lines of evidence support its pre-Clovis assignment.However, by analyzing the tool to debitage ratio amongst the 3 assemblages it appears that the Buttermilk Creek Complex peoples were using the site for a greater diversity of tasks than the Folsom and Clovis peoples.
One overshot flake and 3 partial overshot flakes found in the Buttermilk Creek Complex suggest the possibility that they were starting to develop the knapping technologies that would be indicative of later Clovis technology.
The Buttermilk Creek Complex is found within Vertisols. The Clovis horizon is found below Folsom within a 2.5 cm thick layer containing Clovis diagnostics.
