The Russian Archaeological Project in South America: Principal Findings and Prospects

Abstract

This study outlines the findings of field and laboratory studies by the first Russian archaeological expedition to South America in 2014–2015 and 2017–2018 in collaboration with colleagues from Ecuador and Japan. The project focused on sites of the Archaic (10.8–6.6 ka BP) and Early Formative period (5.5–3.5 ka BP) in the coastal zone of Santa Elena Province, Ecuador. Excavations at Real Alto (Valdivia culture) and Loma Alto (Las Vegas culture) yielded representative archaeological, anthropological, and faunal samples and a large series of AMS dates, providing a basis for a number of novel proposals regarding the chronology and periodization of cultures, their origin, and early pottery-production in South America. Specifically, we have demonstrated that at the very beginning of the Formative period, two early ceramic traditions coexisted—Valdivia and “San Pedro”. We have demonstrated the peculiarity of the “Tropical package” in the stone toolkit, and traced the previously unknown features of the funerary rites of the Las Vegas and Valdivia cultures. Radiocarbon analysis helped to correct the chronology of the late stage of the pre-ceramic Las Vegas culture (8.0–4.8 ka BP) and to estimate the tentative date of the earliest pottery manufacture at 4.8–4.7 ka BP. In conclusion, we outline the top priorities and prospects of Russian archaeological studies on the Pacific coast of South America, underscoring the importance of international cooperation.
