The early occupation of America The Cooper's Ferry archaeological site in western North America has provided evidence for the pattern and time course of the early peopling of the Americas. Davis et al. describe new evidence of human activity from this site, including stemmed projectile points. Radiocarbon dating and Bayesian analysis indicate an age between 16,560 and 15,280 years before present. Humans therefore arrived in the Americas before an inland ice-free corridor had opened, so a… 

Pioneers from Northern Japan in Idaho 16,000 Years Ago? A Critical Evaluation of the Evidence from Cooper’s Ferry

ABSTRACT Davis et al. (2019) recently presented the results of excavations at the Cooper’s Ferry site, located beside the Salmon River in Idaho. They claim that initial occupation of this site dates

Archaeological evidence shows widespread human depopulation of Last Glacial Maximum Northeast Asia

For decades, archaeologists have debated whether Paleolithic humans withdrew from Northeast Asia during the Last Glacial Maximum (LGM), an issue especially important for the Pleistocene peopling of

A critical assessment of claims that human footprints in the Lake Otero basin, New Mexico date to the Last Glacial Maximum

The ancient human footprints in valley-bottom sediments in Tularosa Valley, New Mexico, are fascinating and potentially important because they suggest interactions between Pleistocene megafauna as

Response to Review of “Late Upper Paleolithic occupation at Cooper’s Ferry, Idaho, USA, ∼16,000 years ago” by Fiedel et al.

ABSTRACT In an essay published in PaleoAmerica (2020, Vol. 6, No. 4), Fiedel and coauthors present a review of “Late Upper Paleolithic occupation at Cooper’s Ferry, Idaho, USA, ∼16,000 years ago”, by

Archaeometric studies on rock art at four sites in the northeastern Great Basin of North America

Rock art originated some 46,000 years ago and can provide unique insights into the minds of our human ancestors. However, dating of these ancient images, especially of petroglyphs, remains a

Comment on “Late Upper Paleolithic occupation at Cooper’s Ferry, Idaho, USA, ~16,000 years ago”

TLDR
Critical review suggests that this early date for human occupation at Cooper’s Ferry is not supported by the evidence, and that human occupation might have begun in the mid-16th millennium before the present, but would have been more likely after ~15,000 years ago, coeval with GI-1.

An early dog from southeast Alaska supports a coastal route for the first dog migration into the Americas

TLDR
The results indicate that PCDs were largely replaced by modern European dog breeds, and their population decline started approximately 2000 years BP, coinciding with the expansion of Inuit peoples, who are associated with traditional sled-dog culture.

Archaeological studies at Coxcatlan Cave in the Tehuacan Valley of southern Puebla, Mexico, have been instrumental to the development of the chronology for the region and for our understanding of the

Late date of human arrival to North America: Continental scale differences in stratigraphic integrity of pre-13,000 BP archaeological sites

By 13,000 BP human populations were present across North America, but the exact date of arrival to the continent, especially areas south of the continental ice sheets, remains unclear. Here we

Deglaciation of the Pacific coastal corridor directly preceded the human colonization of the Americas

TLDR
It is concluded that CIS retreat ensured that an open and ecologically viable pathway through southeastern Alaska was available after 17 ka ago, which may have been traversed by early humans as they colonized the Americas.

TLDR
Sporormiella and other proxy evidence from the sediments indicate that hunter-gatherers along the Gulf Coastal Plain coexisted with and utilized megafauna for ~2000 years before these animals became extinct at ~12,600 cal yr B.P.

Evidence of an early projectile point technology in North America at the Gault Site, Texas, USA

TLDR
Age estimates from a series of alluvial sedimentary samples from the earliest cultural assemblage at the Gault Site, Central Texas indicate an early human occupation in North America before at least ~16 thousand years ago, and suggests that Clovis technology spread across an already regionalized, indigenous population.
