Evaluation of the Geoarchaeological Study that Proposes a Middle Holocene Age for Monte Verde II, Chile
The late Pleistocene age of Monte Verde II (MV-II), Chile, has been challenged based on a regional geoarchaeological study of Chinchihuapi Creek [Surovell, T., C. Méndez, J.-L. García, C. Lüthens, J. M. Thompson, and C. Latorre. 2026a. “A Mid-Holocene Age for Monte Verde Challenges the Timeline of Human Colonization of South America.” Science 391: 1283–1288]. The authors of that study propose that the early archaeological component at MV-II dates…
Late Pleistocene paleoenvironments and social dynamics in the southern Lower Mississippi River Valley
Archaeologists studying the Late Pleistocene and Early Holocene records in the Southeast have made significant methodological and theoretical contributions to our understanding of the earliest Native American record. In this paper, we briefly review these contributions. We then present a geographic case study of the southern Lower Mississippi River Valley. Relying on border, behavioral ecological, and cultural transmission theories, we show that …
Theoretical and Methodological Contributions from Researching the Earliest Southeastern Record
We review the contributions of archaeologists studying the Pleistocene and Early Holocene records in the American Southeast. Researchers have made great efforts in finding paleoenvironmental proxies for the past, discovering underwater sites, and embracing a record of isolated point finds. With a renewed interest in technological organization and behavioral ecology, researchers study landscape use as adaptive responses and consider the role of so…
The weathering and scavenging of keratin
The Early Holocene archaeology of Florida
Three of the most influential archaeological models in the southeastern US have argued that early foragers organized their lifeways via seasonal movement along major drainage basins; around access to raw material sources, crossing drainage basins; or around group foraging needs, following central place foraging models. We examine the distribution of Early Holocene Bolen sites in Florida in light of these models by combining Florida Master Site Fi…
Submerged inland landscapes of the Aucilla basin, Northwest Florida, USA
Archaeological data have demonstrated that modern Florida was occupied by at least 14,550 years ago, but evidence of Late Pleistocene and Early Holocene peoples (ca. 14,600–8,000 cal B.P.) is limited to far inland and upland settings, as more than half of Florida’s peninsula was drowned between ca. 21,000–6,000 cal B.P. Rising aquifer levels of the Late Pleistocene allowed some interior sites to preserve within forming river channels, especially …
Reconstructing Terminal Pleistocene-Early Holocene Environmental Change at Page-Ladson, Florida Using Diatom Evidence
The Page-Ladson site, currently buried and submerged in a sinkhole in northwestern Florida, demonstrates evidence of human occupation in North America by 14,550 calendar years ago (cal yr BP). This paper combines new diatom evidence with existing palynological data to strengthen paleoenvironmental interpretations at the site. The Page-Ladson sinkhole was not entirely submerged between ∼15,100 and 14,400 cal yr BP. Conditions at the site became wa…
Crossing the waterline
Over the past decade, research in the Aucilla River of northwestern Florida, USA, has focused upon understanding the geoarchaeological context of numerous formerly-terrestrial, now-inundated sinkhole spring sites and the landscapes surrounding them. Dozens of terminal Pleistocene and early Holocene-aged diagnostic artifacts have been recovered from this river, some in association with drowned terrestrial soils and intact dateable stratigraphy. Cu…
Geoarchaeological framework of Late Pleistocene and Early Holocene sites in the Aucilla River Basin, Northwest Florida, USA
The karstic Aucilla River of Northwest Florida is renowned for its well‐preserved late Pleistocene cultural material and Rancholabrean fauna. Much of this material was recovered by avocational SCUBA divers from displaced contexts in mid‐channel sinkholes, but underwater excavations into sediment banks on sink margins have demonstrated that faunal material and early artifacts can be recovered in situ from inundated terrestrial strata that contain …
