In the archaeological sites of hunter-gatherer societies in Patagonia, carbonized woody plant macro-remains are the most frequent and ubiquitous of the archaeobotanical record. For this reason, it is essential to create a reference collection that allows a correct identification and interpretation of anthracological remains and to infer collection and management practices. The objective of this work is to present the reference collection of woods potentially used by hunter-gatherer societies of the southern coast of Patagonia and the island of Tierra del Fuego. In addition, to create dichotomous keys and to apply the results obtained to the identification of archaeological charcoals from two archaeological sites of the late Holocene of the southern Atlantic coast of Patagonia and Tierra del Fuego (Palo Alto and CSP2017). The importance of this work is due to the few anatomical descriptions for many of the species of the Atlantic coast of Patagonia, especially for taxa that do not have commercial use.
El objetivo de este trabajo es presentar el análisis antracológico de dos sitios de la faja central de la Isla Grande de Tierra del Fuego (Cabo San Pablo 2017 y Kami 7) y discutir la utilización de recursos leñosos por parte de los grupos que habitaron el área durante el Holoceno tardío. Se aplicó una metodología de análisis antracológico estándar, que incluyó la identificación taxonómica, la evaluación de alteraciones en la estructura de los carbones y estimación del calibre original de los leños utilizados. Los resultados demuestran un énfasis en el uso combustible de taxa de la clase fitosociológica Nothofagetea pumilionis-antarcticae, siendo Nothofagus pumilio y N. antartica/betuloides los más abundantes. Se registra una preponderancia de carbones de grandes calibres, de madera colectada en buen estado y alteraciones que reflejan eventos de altas temperaturas de fogón. De los resultados se deduce un aprovechamiento intenso y variado de los bosques cercanos a los sitios.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
