英文摘要: This contribution aims to analyse the best-known paleovertebrate records from the beginning of the Late Pleistocene in Salto Ander Egg Formation (SAEF), Argentina. This fossil assemblage allowed us to infer the paleoenvironmental conditions for these deposits, and to discuss the biostratigraphic record within a geochronological framework. Salto Ander Egg Formation (SAEF), mapped in southwestern Entre Ríos province, is composed of fluvial deposits and was dated with ages ranging from 120 to 60 ky. Three sub-sequences were identified in the succession, which suggests a transgressive cycle over the MIS5 composed of a rising trend during MIS5e, a high stand stage in MIS5c, and a minor transgressive cycle during MIS3. A quantitative analysis has shown that approximately 50% of the total richness estimated for the unit has been sampled up to the moment. Two biostratigraphic units could be discriminated based on the study of faunistic associations. One of them, with Brazilian fauna, is linked to the basal sequences of SAEF (SS1). The other, exhibiting Pampean affinities, corresponds to middle and upper levels of SAEF (SS2–SS3). © 2016 Citation statistics:
