- Environmental variation in the early and middle Holocene in Tequendama and Aguazuque archaeological sites, Colombia Angélica Viviana Triana Vega Víctor Adrián Pérez Crespo Ciencias de la Tierra hunter Colombia gatherers phytoliths Sabana de Bogotá This study focuses on identifying possible environmental variations and plant availability during the occupation in two archaeological sites: Tequendama and Aguazuque, located in Sabana de Bogotá, Colombia. Those sites represent periods of occupation during the early to middle Holocene that contributes valuable information about hunter-gatherers who occupied this area. Data obtained and recovered archaeological material during excavations shed light on relatively continuous occupations until the late Holocene. The presence of lithic artefacts, human and fauna bone remains offered relevant information to comprehend social dynamics among these human groups; likewise, phytolith and stable isotope analysis on sediments and fauna were carried out to identify environmental variations, and the presence of plant remains in these archaeological contexts. Carbon isotope analysis in sediments indicated the prevalence of plants C3 from the early Holocene. In turn, isotopic relationships in carbon obtained from mammals’ dental enamel found in both sites suggest that those animals consumed such types of plants. Also, isotopic values in oxygen from dental enamel show humid and possibly cold environmental conditions in both locations. Also, phytolith analyses provide evidence on the types of plants available in determined contexts and reconstruct environments, use, and availability. Those three types of analysis were applied to archaeological contexts to determine the presence of plants type C3 or C4 available in the sites, which permitted to evidence of environmental changes, humid conditions, and, in a few cases, drought across occupation, as well as the differences in terms of the presence or absence of certain types of plants during chronological periods, suggesting a possible association of horticultural processes and domestication during middle Holocene in Aguazuque archaeological site. 2022 artículo científico 1405-3322 https://www.redalyc.org/articulo.oa?id=94375433011 https://www.redalyc.org/journal/943/94375433011/ https://www.redalyc.org/journal/943/94375433011/html/ https://www.redalyc.org/journal/943/94375433011/94375433011.epub https://www.redalyc.org/journal/943/94375433011/movil https://doi.org/10.18268/BSGM2022v74n3a140622 en http://www.redalyc.org/revista.oa?id=943 Boletín de la Sociedad Geológica Mexicana application/pdf Sociedad Geológica Mexicana, A.C.
