“…Within the overall context of the Late Pleistocene, the mammalian assemblage recorded from ELU consists of a semiarboreal marsupial, Hydrochoerinae and Myocastorinae semiaquatic rodents, freshwater continental fishes and South American native ungulates, amongst others (see Vezzosi ; Vallone et al . ; Vezzosi et al . ).…”

“…The fossil specifically comes from the basal fluvial deposits informally referred to as the Esperanza Lithostratigraphic Unit (ELU; Fig. 2), which is extremely fossiliferous with both aquatic and continental vertebrates (Vezzosi 2015;Vallone et al 2017;) and constitutes a tabular stratum composed of pale olive fine sands and silts that range from diffusively stratified to horizontally laminated. Frequent iron oxide segregations can be observed macroscopically.…”

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).

Armored catfish (Siluriformes: Loricariidae) from the Miocene of southern Pampas and its palaeobiogeographical implications

Armored catfishes are grouped within the clade Loricariidae. They are typically Brazilian freshwater fishes that show a high taxonomic diversity in South America and are distributed from Costa Rica to Buenos Aires province, Argentina. The aim of the present contribution is to describe an isolated pectoral spine of a loricariid coming from Late Miocene beds of southern Pampas, at Buenos Aires province, Argentina. This record constitutes the first finding of a fish in the Chasicó area, Arenas Blancas fossiliferous site, and is located far from the current geographical range of loricariids. The finding of a loricariid is congruent with the idea of a warm climate and the possibility that southern paleobasins of Pampas and northern Patagonia were hydrographically connected with paleobasins that hold Brazilian freshwater fishes.
