Among these, mammals have particular importance since their record shows some taxonomic peculiarities when compared with that of adjacent units. Here we describe new material that includes Notoungulata of generalized morphology, two morphotypes of basal typotherians, and two interatheriid taxa (including \u003ci\u003eAntofagastia turneri\u003c/i\u003e gen. et sp. nov.). These findings increase the variety of groups and provide new information about previously known taxa for this unit. Three phylogenetic analyses with different taxonomic contexts were performed. The first analysis includes the specimen referred to as ‘Typotheria indet. A’ in a data matrix of Paleogene notoungulates containing taxa traditionally referred as ‘Oldfieldthomasiidae’. The specimen is grouped together with three ‘oldfielthomasiids’ (\u003ci\u003eMaxschlosseria\u003c/i\u003e, \u003ci\u003eUltrapithecus\u003c/i\u003e and \u003ci\u003eDolichostylodon\u003c/i\u003e) in the resulting tree. The second analysis involves specimens referred to as ‘Typotheria indet. B’, ‘archaeohyracids’, mesotheriids and hegetotheriids. The results show these fossils to be part of a basal polytomy of ‘early archaeohyracids’. Finally, a third analysis was conducted with Interatheriidae as the ingroup which recovered \u003ci\u003eAntofagastia turneri\u003c/i\u003e at the base of a node including extra-Patagonian forms of non-interatheriine interatheriids plus \u003ci\u003eEopachyrucos\u003c/i\u003e and interatheriines. Although \u003ci\u003eAntofagastia\u003c/i\u003e, \u003ci\u003ePunapithecus\u003c/i\u003e and Chilean extra-Patagonian forms share some features, such as small size, they do not comprise a distinct clade. The notoungulate record of the Geste Formation shows some singularities in the context of north-western Argentinean Paleogene units, the presence of interatheriids and ‘archaeohyracids’ being the most striking of these. The differences exhibited can be partially explained by temporal factors, since recent isotopic data points to a Late Eocene age for this unit. Biogeographical isolation represents another possible explanation, because these levels appear to be deposited in an isolated geographical and geological context, suggesting intermontane basin deposition or local wedge-top basins.http://zoobank.org/urn:lsid:zoobank.org:pub:690E818B-D2CD-4E93-9C34-8305E8D7F847","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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
