During the decade of 1980, fossil mammals were recovered from an unnamed lithostratigraphic unit in Agua de Flores (south Mendoza Province). These fossils allowed recognizing a middle Eocene age for the sediments for the first time in this provincial area. Later, new discoveries in Cenozoic deposits of a very near locality, Agua de Isaac, confirmed the presence of middle Eocene levels in this zone. A little southern, a Tertiary geologic unit, the Puesto Fortunata Formation, had been defined at Anfiteatro Liu Malal locality, but without assigning a precise age to it within the Cenozoic. In this context, the objective of this contribution deals with the correlation of these different Cenozoic deposits within a regional framework. Based on lithological characterization, we consider them to correspond to the same unit, the already defined Puesto Fortunata Formation, which is assigned to middle Eocene based on paleontological content.
