The site of El Triunfo is located near to the modern village of Versalles in the Department of the Beni, Bolivia, on the Guapore River along the southern rim of the Amazon. The site is located next to Laguna Versalles, a closed lake with a 50,000 year sequence of sediment deposition that records the long-term regional vegetation history. Investigations at El Triunfo in 2016/17 revealed a rich ceramic tradition, earthworks, and distinct associations of economic plants with anthropogenic Amazonian Dark Earth’s. Based on the continuous C3 signal the data suggests that they practice agroforestry. The research at El Triunfo targets human/environment dynamics through combined paleoecological and archaeological methods. This paper presents the current findings from integrated phytolith, geochemical and isotopic analyses from excavations, detailing specific plant use and human impacts on the vegetation.
