“…1A-B). At this site, two formations, assigned to the Middle-Late Pleistocene, are present: the Puerto San Martín Formation and the Timbúes Formation overlying the former (Vezzosi and Kerber, 2018;Vezzosi et al, 2018). However, the exact stratigraphic provenance of (MACN-Pv 11555) is unknown.…”

“…Several litostratigraphic units are recognized for the Pleistocene of the lower Carcarañá River catchment (e.g., Puerto San Martín Formation, Timbúes Formation, Carcarañá Formation, Tezanos Pinto Formation; Kröhling, 1999;Iriondo and Kröhling, 2009;Iriondo, 2010;Kröhling and Carignano, 2014). Some of these sequences range from late Middle to Late Pleistocene and are extremely fossiliferous with both aquatic and continental vertebrates (Frenguelli, 1928a;Brandoni and McDonald, 2015;Vezzosi, 2016;Vallone et al, 2017;Vezzosi et al, 2017Vezzosi et al, , 2018.…”

“…Late Pleistocene units are recognized along the cut banks of the Carcarañá River; and include the Timbúes, Carcarañá and Tezanos Pinto Formations (Kröhling, 1999;and Carignano, 2014;Vezzosi, 2015), outcropping together with Holocene deposits (e.g., Lucio López/San Guillermo Formations; Kröhling, 1999;Iriondo, 2010, Kröhling andCarignano, 2014). The Timbúes Formation was described at the outlet of the Carcarañá River draining into the Paraná River (32°36'40.99"S -60°45'34.28"W) (Iriondo and Kröhling, 2009), but preserves scare fossil mammal remains (Vezzosi and Kerber, 2018). It is noteworthy that the first fossil materials (i.e.…”

In this contribution the record of a Nothrotheriinae (Xenarthra, Tardigrada) ground sloth is reported from the Late Pleistocene of the Northern Pampa of Santa Fe Province, Argentina. The stratigraphic unit where the fossil was collected corresponds to fluvial-palustrine sediments of the Timbúes Formation, outcropping along the Carcarañá River valley. The relative stratigraphic position of this lithostratigraphic unit, observed in several sections mainly on the Paraná River cliffs near Carcarañá River distal area, suggests that it was deposited during the Last Interglacial Stage.The specimen (MPAHND-135), assigned to Nothrotherium cf. torresi, is represented by the proximal two-thirds of a left femur that shows a prominent lesser trochanter and no connection between the third trochanter and the ectepicondyle. The presence of Nothrotherium cf. torresi in sediments related to humid conditions supports the idea that Nothrotheriinae had great ecological tolerance and was capable of inhabiting climates ranging from cold and arid, as was previously proposed, to warm and humid.

The aim of this contribution is to describe a femur (MCRS 199) assigned to Nothrotheriops sp. from the Late Pleistocene of Santa Fe Province (Argentina), and discuss the implications of this find in the context of the dispersal of ground sloths during the Great American Biotic Interchange. The specimen MCRS 199 is smaller than the femora referred to the North American species Nothrotheriops texanus and Nothrotheriops shastensis but shares several features with these species: (i) shape and position of the greater trochanter, (ii) development of the lesser trochanter, (iii) presence of connection between the third trochanter and the ectepicondyle, (iv) distal third of the femur wider, with ML/DW index of 1.93, and (v) location and relationship of the distal condyles. These similarities allow us to assign MCRS 199 to Nothrotheriops sp. The record of Nothrotheriops sp. from Santa Fe Province chronologically coincides with the earliest records of Nothrotheriops shastensis suggesting a broad geographical distribution of Nothrotheriops during the Late Pleistocene, ranging from 33–36°N (e.g. states of California and Arizona, USA) to 31°S (northern Salado River, Santa Fe Province, Argentina). Thus, Nothrotheriops have dispersed from North America (where Nothrotheriops has early records, Calabrian–Middle Pleistocene) to South America where localities bearing Nothrotheriops are Late Pleistocene in age. In addition, once in South America and probably during the Middle Pleistocene, Nothrotheriops probably gave rise to its sister taxon, Nothrotherium, with records from the Middle Pleistocene (e.g. 223 ka BP, northeastern Brazil) to the Late Pleistocene (e.g. 15 ka BP).
