| English abstract | This study presents the results of a quantitative analysis of calcareous nannofossils recovered from subsurface samples in drilled wells at the locality of Cerro Redondo, southeastern Santa Cruz Province, Austral Basin of Argentina. Index species identified in the succession allow to recognize stratigraphic levels in the early and middle Paleocene, the late early Eocene and middle Eocene. The basal level of the Paleogene was established based on the Cretaceous-Paleogene interval, which includes an unconformity from the middle Maastrichtian to the lowest Paleocene. It has been inferred high sea and superficial cold water condition for the Paleocene and middle Eocene and shore-face condition during the late middle Eocene |
