PEREZ, ALBERTO E and ERRA, GEORGINA. Identificación de maiz de vasijas recuperadas de la Patagonia noroccidental argentinaIdentifying maize residues in pottery vessels in northwestern Patagonia, Argentina. Magallania [online]. 2011, vol.39, n.2, pp. 309-316. ISSN 0718-2244. http://dx.doi.org/10.4067/S0718-22442011000200022.
Plant opal silica bodies (phytoliths) obtained from scraped food residues from the inside walls of pottery vessels are described and identifed as maize (Zea mays, Poaceae) cob bodies. These vessels come from the archaeological locality of Meliquina (-40° 19´S -71° 19´W), Lácar Department and Lanín National Park, Patagonia, Argentina and were dated between 730 ± 80 bP and 920 ± 60 bP. The presence of short-cell phytoliths diagnostic of maize cobs, called wavy-top rondels and ruffe-top rondels from the Zea mays (maize) is highlighted. It constitutes the southernmost preincaic record in the continent, whose origin is related to environmental conditions of low humidity, which would have affected social mobility and the trade of goods through long distances from east to west, with the societies of the central valleys of mid-southern Chile settled to the east of the Andean range between 1,000 and 700 years b P.
