The 13,900-Year-Old Mastodon Rib Found With A Bone Point Still Inside — And The CT Scan That Put Hunters Before Clovis
The Clovis-first model was not just an archaeological interpretation.
It was, for many researchers, an intellectual framework that shaped how every new site was interpreted.
Sites that produced dates earlier than Clovis, or that claimed evidence of human presence without Clovis-type tools, were viewed through a lens of skepticism that was, in some cases, more stringent than the lens applied to Clovis sites themselves.
The first serious cracks in the Clovis-first consensus appeared in the 1970s and 1980s.
Tom Dillehay’s excavation of Monte Verde in southern Chile produced evidence of human occupation dating to approximately 14,500 calibrated years before the present — more than a thousand years before the accepted Clovis horizon.
