Landscape and environmental conditions for the late Holocene in the eastern Pampa-Patagonia transition (Argentina): a phytolith analysis of the El Tigre archaeological site

Vegetation History and Archaeobotany, 2021
The El Tigre archaeological site (39°46′49″ S; 62°22′32″ W) is located in the south of Provincia de Buenos Aires, Argentina, on an ancient delta of the Rio Colorado. Its sedimentary sequence shows periods of landscape stability and soil formation processes during the period ca. 1,000–400 years bp.

First analysis of mitochondrial lineages from the eastern Pampa–Patagonia transition during the final late Holocene

American Journal of Physical Anthropology, 2020
AbstractObjectiveStudies on population genetics have become highly relevant for understanding the evolutionary history of human settlement in southern South America. The eastern Pampa–Patagonia transition is an area that stands out due to its complex population dynamics, especially during the last about 1,000 years BP.

Petrographic thin sections and exotic rocks provenience among hunter–gatherer societies in the eastern Pampa–Patagonia Transition (lower basin of the Colorado River, Argentina)*

Archaeometry, 2020
Lithic assemblages recovered from sites located in the eastern Pampa–Patagonia transition include a great diversity of raw materials, some from neighbouring regions, such as the Humid and Dry Pampa subregions and Northpatagonia. Lithic raw material assignments to specific procurement areas were preliminarily proposed based on macroscopic ...

First anthrachological studies at the eastern Pampa-Patagonia transition (Argentina). Hunter-gatherers management of woody material and Initial Late Holocene vegetal communities inferred from the Zoko Andi 1 archaeological site

Journal of Arid Environments, 2021
Abstract In the lower basin of the Colorado River (Buenos Aires province, Argentina) the Zoko Andi 1 archaeological site was occupied by hunter-gatherer groups during the Late Holocene (ca. 1500–400 14C years BP). The site is the only one in the entire study area that has an important presence of charcoals in a stratigraphic context, particularly ...

Feeding patterns of marine euryhaline fish and their impact on hunter-gatherer diets during the Mid-Late Holocene in the eastern Pampa-Patagonia transition (Argentina)

Journal of Archaeological Science: Reports
Subsistence has been one of the most widely discussed topics concerning the archaeology of hunter-gatherer groups who inhabited the eastern Pampa-Patagonia transition (Argentina) since ca. 6000 years BP. Previous studies on human paleodiets through the analysis of stable isotopes (δ13Cap, δ13Ccol and δ15N) indicate that during the Middle Holocene ...

Human occupation, site formation, and chronostratigraphy of a mid-Holocene archaeological site at the eastern Pampa-Patagonia transition, Argentina

Quaternary Research, 2023
AbstractIntense aeolian processes in arid and semi-arid environments play an essential role in the preservation and destruction of archeological sites. This is especially the case in the lower basin of the Colorado River at the eastern Pampa-Patagonia Transition of Argentina, as is illustrated by geoarchaeological and chronostratigraphic studies at a ...

Size estimation based on Genidens barbus and Micropogonias furnieri otoliths. Exploring Late Holocene euryhaline fish capture techniques in the eastern Pampa–Patagonia transition, Argentina

The Journal of Island and Coastal Archaeology, 2023
Sea catfish (Genidens barbus) and whitemouth croaker (Micropogonias furnieri) were the most marine euryhaline species exploited by hunter-gatherers during the final Late Holocene along the coastal fringe of the eastern Pampa–Patagonia transition (Argentina).
