Desde una perspectiva tecnológica, se estudiarán conjuntamente los objetos líticos recuperados en cada uno de estos yacimientos, incidiendo en la relevancia de las conclusiones obtenidas para el conocimiento del Olduvayense africano.Ĭyanobacteria and cyanobacterial toxins in the alkaline-saline. Este complejo está constituido por un grupo de 11 yacimientos arqueológicos muy próximos topográficamente y situados en la misma posición estratigráfica, por encima de la Toba 1 en las Upper Sandy Cáliz (Arcillas Arenosas Superiores de la Formación Humbu de Peninj, cuya cronología se estima entre los 1,6-1,4 ma. Lithic artefacts from each archaeological site will be analysed together from a technological perspective, focusing on the relevance of the conclusions obtained for knowledge of the African Oldowan.Įn este trabajo se presenta un análisis sistemático de los materiales líticos hasta ahora estudiados en el Complejo ST de Peninj, en el lago Natron (Tanzania. They are located above Tuff 1 in the Upper Sandy Clays of the Humbu Formation of Peninj, dated around 1,6-1,4 ma.
