Resumen:
MIS 3 (Marine Isotope Stage 3, 60-25 ka BP) corresponds to a long interstadial episode considered generally warmer than MIS 2 and 4, and including numerous and abrupt Dansgaard-Oeschger and Heinrich events, sometimes brief but very intense. The materials studied here, coming from the Late Pleistocene outcroppings in central-north Mesopotamia (Corrientes province, Argentina, Toropí/Yupoí Fm., MIS 3; ca. 52-36 ka BP), is characterized by the presence of a large and complex vertebrate assemblage, being the Cingulata (Xenarthra) one of the most frequently represented taxa. In this work we provide an updated list of cingulates from Corrientes province, referrable to the Late Pleistocene, after performing new collections in the area and revising previous determinations. This includes: a) Dasypodidae: Propraopus sulcatus Lund, Euphractus aff. E. sexcinctus Linnaeus; Chaetophractus villosus (Desmarest); b) Pampatheriidae: Holmesina paulacoutoi (Cartelle-Guerra and Mahecha-Bohorquez), Pampatherium sp., Pampatherium typum Ameghino; c) Glyptodontidae: Panochthus tuberculatus (Owen 1845), Panochthus sp., Glyptodon reticulatus Owen, Glyptodon sp., Neosclerocalyptus paskoensis (Zurita), Neosclerocalyptus cf. N. paskoensis (Zurita), Neosclerocalyptus sp Using this information, their diversity is compared with that of Late Pleistocene cingulates faunas described for sediments from areas currently located in the provinces of Formosa and Buenos Aires (Argentina), northern Uruguay and southern Brazil. Lastly, palaeoclimatic and palaeobiogeographic aspects that may be inferred from the study of this assemblage are discussed in the context of the MIS 3. Even though the taxa recorded are not new, the relative occurrence of each one shows evident differences with those in other areas.
