Condiciones paleoambientales y ocupaciones humanas en el sitio Familia Primón (Coronda, Santa Fe): aportes desde la arqueopalinología

In this paper, we present the results of pollen analysis carried out at the Familia Primon archaeological site, located in a transitional area of the Parana River floodplain (Santa Fe, Argentina). The aim of this study was to undertake a preliminary analysis of the  archaeopalynological assemblage, and thereby provide an insight into the availability of plant resources that might have been used by hunter-gatherers in the past. In so doing, the identification and interpretation of the pollen recovered from the site was carried out. The collated record shows a first pollen zone characterized by the predominance of herbaceous and arboreal-bushes, typical of a xerophilous forest. A second zone was observed around the 470±50 years BP mark. This zone suggests a relative increase in humidity, given the presence of typical vegetal taxa ( v.g. Prosopis sp., Celtis sp. and Syagrus romanzoffiana ) that have intrinsic qualities useful for the human subsistence.
