Nothrotherium CF.N.Maquinense (xenarthra, tardigrada) in the sopas formation (late pleistocene of Uruguay)

The quaternary continental Sopas Formation of Uruguay shows a faunal moisture which joins typical representatives of the pampean region with components of northern origin. Remains assigned to the Family Nothrotheriidae were mentioned for this unit on the basis of very fragmented material. The presence of the genus Nothrotherium in the Sopas Formation is confirmed, the finding of the species Nothrotherium. cf. N. maquinense is communicated, and the corresponding remain is described, a right mandibular ramus. N. maquinense was distributed in the territory today named Brazil during the Late Pleistocene – Early Holocene lapse, in a diverse tropical climate which favored the development of savanna vegetation. The chronology and environments inferred from this finding are not contradictory with the previous proposals for the Sopas Formation
