First mammal remains from this area go back to the 1930s, but only three taxa were recognized since then, two notoungulates, the mesotheriid Typotheriopsis silveyrai and the hegetotheriid Hemihegetotherium achathaleptum, and the caviid rodent Cardiatherium paranense. A recent project, focused on geological and paleontological aspects of the Tupungato\u2013Piedras Coloradas Anticlines, has allowed us to improve the geological knowledge of the area and increase its faunal diversity. This is one of the best localities for the study of the uppermost section of the Cacheuta foreland basin, and we present the first detailed section of the R\u00edo de los Pozos Formation (including part of previously considered Mogotes Formation). Concerning fossils, xenarthrans (sloths and armadillos), pachyrukhine hegetotheriids, a toxodontid, and different families of rodents (Chinchillidae, Octodontidae, Caviidae Dolichotinae, and Abrocomidae) are recognized for the first time in this locality, together with new remains of T. silveyrai, H. achathaleptum, and C. paranense. The comparison with Late Miocene\u2013Pliocene Argentinean faunas reveals general similarities with most assemblages assigned to the Huayquerian Stage\/Age, somewhat closer to those from the Cerro Azul Formation, and there are also shared taxa with Early Pliocene faunas. The biostratigraphic data presented here agree with published ages obtained for the R\u00edo de los Pozos Formation in the La Pilona Anticline."],"dc:format":["application\/vnd.openxmlformats-officedocument.wordprocessingml.document"],"dc:language":["eng"],"dc:type":"dataset","dc:rights":["info:eu-repo\/semantics\/restrictedAccess","Datos sujetos al derecho de propiedad intelectual"],"dc:relation":["info:eu-repo\/grantAgreement\/Ministerio de Ciencia, Tecnolog\u00eda e Innovaci\u00f3n Productiva\/2017-0797"],"dc:identifier":"https:\/\/repositoriosdigitales.mincyt.gob.ar\/vufind\/Record\/CONICETDig_cbcd6ad641503af672ad1666478c9fed"}
