“…5A). It is also the most abundant rodent in the Santa Cruz Formation (Scott, 1905;Croft, 2013;Arnal et al, 2019;Zurita-Altamirano et al, 2019) but is much less abundant in the Pinturas Formation (Kramarz and Bellosi, 2005;Kramarz, 2006b). Even if the number of specimens of N. australis and N. pinturensis are combined, they do not dominate the fauna of the Pinturas Formation to the degree that N. australis does at Pampa Castillo or localities in the Santa Cruz Formation (Arnal et al, 2019).…”

Caviomorph rodents became important components of South American faunas after their Eocene arrival from Africa. Here we describe the cavioid, chinchilloid, and erethizontoid caviomorphs of the early Miocene Pampa Castillo fauna of southern Chile. This fauna's age and location make it key for resolving outstanding biostratigraphic questions concerning early Miocene Patagonian fossiliferous strata.Each of the four major caviomorph clades ("superfamilies") is represented in the Pampa Castillo fauna, three whose members are detailed here: cavioids (3 genera; 3 species), chinchilloids (3 genera; 6 species), and erethizontoids (2 genera; 2 species).Abundantly represented taxa, e.g., Neoreomys australis, Perimys erutus, and Prolagostomus pusillus, corroborate previous work assigning the Pampa Castillo fauna to the Santacrucian South American Land Mammal "Age" (SALMA; inclusive of the "Pinturan"). Several taxa, including Eosteiromys, Perimys intermedius, and Perimys sp. nov.?, are also found in the lower and middle Pinturas Formation (ImPF) but not "core" Santacrucian faunas (from the Santa Cruz Formation [SCF] along the Rio Santa Cruz and Atlantic coast), suggesting a distinctive

“…After more than 200 years of collecting around the world, some collections are now forgotten, lost, or understudied. In Europe, recently, several institutions are trying to highlight the most significant paleontological collection of mammals (e.g., Carrillo-Briceño et al, 2016 ; Solé et al, 2020 ; Van der Hoek, 2021 ; Vera et al, 2015 ; Zurita-Altamirano et al, 2019 ), a primacy for paleontological community. An example is the significant collection of Pleistocene megafauna from South America assembled by Santiago Roth.…”

The present work concerns xenarthrans from the collection of Santiago (Kaspar Jakob) Roth (1850–1924) housed at the Palaeontological Institute and Museum of the University of Zurich, one of the most important collections of Pleistocene mammals from Argentina in Europe. Roth was a paleontologist originally from Switzerland who prospected and collected a large amount of Pleistocene megafauna of the Pampean Region of Argentina. The xenarthrans are the main representatives of this collection in Zurich, with 150 specimens. Since 1920, this material has not been revised and is under studied. The present investigation corresponds to a taxonomic revision resulting in 114 reassignments, leading to document xenarthran diversity and discuss their paleoecologies. The high diversity reflects the paleoecology of the Pampean Region during the Pleistocene, with the various abiotic events that impacted the paleoenvironment of this region. Within the Cingulata, the Pampean Region fauna was probably dominated by glyptodonts with a high representation of Glyptodontinae and Neosclerocalyptinae while within the sloths the highest diversity and abundance is found in the Mylodontinae and Scelidotheriinae. These four clades represent both species with high ecological tolerance (e.g., Glyptodon munizi; Catonyx tarijensis) and ecologically highly specialized species (e.g., Neosclerocalyptus paskoensis; Scelidotherium leptocephalum). The presence of such ecological diversity underlines the status of the Pampean Region as a major interest for paleoecological and paleoenvironmental reconstruction.

“…The collections of fossil mammals made by early explorers in South America during the 19th and beginning of the 20th centuries have been fundamental to reveal the past diversity of South American mammals and unravel their evolutionary history (Defler, 2019 ; Fariña et al, 2013 ; Hatcher, 1985 ; Vizcaíno et al, 2017 ). These collections continue to be studied, some even recently highlighted for the first time (e.g., Carrillo-Briceño et al, 2016 , 2021 ; Zurita-Altamirano et al, 2019 ), and have great historical and scientific value (Vizcaíno et al, 2017 ). One of the most important early fossil collectors in Argentina was the Swiss-Argentine palaeontologist Kaspar Jacob Roth, known as Santiago Roth (1850–1924), who made significant collections of fossil mammals that are housed in museums in Europe and Argentina (Bond, 1999a ; Hansen, 2019 ; Sánchez-Villagra et al, 2023 ; Voglino et al, 2023 ).…”

The fossil collections made by early explorers in South America have been fundamental to reveal the past diversity of extinct mammals and unravel their evolutionary history. One important early explorer in South America was the Swiss-Argentine palaeontologist Kaspar Jacob Roth, known as Santiago Roth (1850, Herisau, Switzerland-1924, Buenos Aires, Argentina), who made significant collections of fossil mammals that are housed in museums in Europe and Argentina. The important collections of Roth in Switzerland include iconic Pleistocene megafauna from the Pampean Region (Argentina). The palaeontological significance of the Pampean Region relies on its abundant record of fossil vertebrates that documents diversity dynamics and paleoenvironmental change in southern South America, serving as the basis for the South American biostratigraphical scale of the late Neogene and Quaternary. The South American native ungulates (SANUs) were hoofed placental mammals that radiated in South America. The clades Notoungulata and Litopterna include, among others, the last representatives of SANUs megafauna in the continent. We revise and describe for the first time the SANUs specimens from the Pampean Region of the Roth collections in Switzerland. The collections include two species of notoungulates (Toxodon cf. T. platensis and Mesotherium cristatum) and one litoptern species (Macrauchenia patachonica). The occurrences are restricted to the early and middle Pleistocene (pre-Lujanian Stages/Ages). Although the SANUs diversity in the Roth collections is low in comparison with other groups (e.g., xenarthrans), some of the specimens are very complete, including skulls and postcranial remains. The completeness of the Ma. patachonica material allows an update and reinterpretation of some of the details of the dentition and the postcranial skeleton of this iconic species. In addition to its historical importance, the SANU specimens from the Roth collections provide important information to study the paleobiology and evolution of South American megafauna and evaluate hypotheses about their extinction in the continent.
