The Arroyo Seco 2 site contains a rich archaeological record, exceptional for South America, to explain the expansion of Homo sapiens into the Americas and their interaction with extinct Pleistocene mammals. The following paper provides a detailed overview of material remains found in the earliest cultural episodes at this multi-component site, dated between ca. 12,170 14C yrs B.P. (ca. 14,064 cal yrs B.P.) and 11,180 14C yrs B.P. (ca. 13,068 cal yrs B.P.). Evidence of early occupations includes the presence of lithic tools, a concentration of Pleistocene species remains, human-induced fractured animal bones, and a selection of skeletal parts of extinct fauna. The occurrence of hunter-gatherers in the Southern Cone at ca. 14,000 cal yrs B.P. is added to the growing list of American sites that indicate a human occupation earlier than the Clovis dispersal episode, but posterior to the onset of the deglaciation of the Last Glacial Maximum (LGM) in the North America.
First, the site presents an ample temporal scale of human occupation from ca. 12,170 14C yrs B.P. to the 19th century. This extensive chronological dimension in a relatively short stratigraphic sequence (~2 m) of loessial sediments assigned to the La Postrera Formation (Fig 2) has been one of the main causes of its low archaeological resolution. Second, there exists a high diversity of archaeological materials which provide a broad spectrum for detailed analysis (lithic, bone, ceramic, etc.) . Third, the site presents an exceptionally varied and abundant number of human burials (50 individuals and counting), dated between 7805 ± 85 14C yrs B.P. and 4487 ± 45 14C yrs B.P. (n = 25 dates) .

Am I doing something wrong? When I click your link, it just brings me to a page with photos of lithics, no article.
Great find, I was just stoked to read more about it. You know me and my devotion to due diligence lol. If I'm doing something wrong, it's ok to bust my balls and have a laugh at my expense. If not and you can link me the pertinent info I would be much obliged. As always, thanks for posting this, it's a pretty important site. I'd love I see some dates on the remains they found at the site.

Havlock's 2008 ATS thread re southwestern-Pennsylvania's Meadowcroft Rockshelter that served as a campsite for prehistoric hunters and gatherers ~16,000 years ago. About one-third of site remains undisturbed.
Meadowcroft Rockshelter and Historic Village, Avella, PA.
I enjoyed the opening... it all started with a groundhog hole in 1955.

But interestingly enough as hyper focused on the "clovis dispersal" as some academics can be, they seem to miss the fact that this clovis dispersal runs against the flow of humanity into the new world, according to the most widely accepted theories.

Especially if the continents were empty of any prior humans to compete for resources, they could make for fast dispersal. 1000 years may even be too long of an estimate for small bands of humans to walk all over the place. Why not? High mortality rates? Low birth survival rates? Bad luck?
