Resumen:
Scelidotheriinae (Mammalia, Pilosa) is a xenarthran mylodontid clade recorded in much ofSouth America from the middle Miocene to the early Holocene. However, studies of theirNeogene representatives are still scarce compared to their Quaternary representatives. Themain goal of this contribution is to report new remains of Proscelidodon rothi (Ameghino,1908) found in the basal levels of the El Polvorín Formation (Pliocene), cropping out nearthe city of Olavarría (Buenos Aires Province, Argentina). On the basis of the faunistic asso-ciation, these deposits were assigned to the late Pliocene. The new materials include askull, a mandible, and a calcaneal fragment (Xen-121), which enhance the characterizationof this taxon, and allow more precise comparisons with other Neogene and QuaternaryScelidotheriinae. This new record extends the biochron and geographic distribution of thespecies, until now recorded in the latest Pliocene (Marplatan Stage/Age, Vorohuean Subage)of Olavarría.
