The aim of this communication is to analyze different aspects related to an abundant ichnofauna recorded in the Río Seco de los Castaños Formation in the Bloque de San Rafael, Mendoza Province, Argentina. These aspects include: i) the discussion of the age of the unit from both biostratigraphic and absolute dating methods; ii) the analysis of the facies scheme previously suggested for the unit; iii) the documentation of the trace-fossil content; and iv) the analysis of the impact of the re-consideration of the age of the unit in ichnostratigraphic schemes.
