“…In addition, five types of uncarbonized seeds were recovered in flotation (see Table B -3). Uncarbonized seeds are a common occurrence on most archaeological sites, but they usually represent seeds of modern plants that have made their way into the soil either through their own dispersal mechanisms or by faunalturbation, floralturbation, or argilliturbation (Bryant 1985:51-52;Keepax 1977;Miksicek 1987:231-232). In all except the driest areas of North America, uncarbonized plant material on open-air sites can be assumed to be of modern origin unless compelling evidence suggests otherwise (Lopinot and Brussell 1982;Miksicek 1987:231).…”

“…Teniendo en cuenta que no sólo la conducta humana actúa en la formación del registro arqueobotánico y que distintos factores tales como la conservación diferencial y la cantidad de semillas que produce una planta son, entre otras, las variables a tener en cuenta al momento de cuantificar e interpretar el registro arqueobotánico (Buxó 1997;Keepax 1977;Minnis 1981), se utilizaron métodos de análisis que ayudaron a diferenciar los posibles orígenes de los carporrestos encontrados en los sitios. De esta forma, los trabajos de campo incluyeron además, la realización de dos sondeos en las proximidades de cada uno de los sitios analizados.…”

“…De esta forma, los trabajos de campo incluyeron además, la realización de dos sondeos en las proximidades de cada uno de los sitios analizados. El objetivo de los mismos fue controlar la forma en que las plantas locales se dispersan naturalmente sin intervención humana, aislando de este modo variables que ayuden a identificar el impacto de la actividad antrópica en el sitio (Keepax 1977;Miksicek 1987;Minnis 1981). Para los sondeos, la metodología utilizada fue la excavación de un pozo de 40x40 cm de donde se extrajeron niveles artificiales de 10 cm llegando hasta el nivel de rodados que impedían seguir con los mismos.…”

“…We have already seen a summary of the history of archaeological flotation and a comparative description of the major flotation techniques (Watson 1976). One researcher has examined the cost-effectiveness of different systems in the United Kingdom (Keeley 1978), and several others have broached the subject of contamination of archaeological samples with modern seeds (Kaplan and Maina 1977;Keepax 1977).…”
