No evidence for parallel evolution of cursorial limb adaptations among Neogene South American native ungulates (SANUs). [PDF]
PLoS ONE, 2021 During the Neogene, many North American ungulates evolved longer limbs. Presumably, this allowed them to move more efficiently or quickly in open habitats, which became more common during this interval.

Pleistocene South American native ungulates (Notoungulata and Litopterna) of the historical Roth collections in Switzerland, from the Pampean Region of Argentina [PDF]
Swiss Journal of Palaeontology, 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.

New Eocene South American native ungulates from the Quebrada de los Colorados Formation at Los Cardones National Park, Argentina [PDF]
Acta Palaeontologica Polonica, 2021 In the last few years, the Quebrada de Los Colorados Formation has become an important middle Eocene fossiliferous unit in Northwestern Argentina. In this unit, the South American native ungulates were until now only represented by the order Notoungulata,

Out of Africa: A New Afrotheria Lineage Rises From Extinct South American Mammals
Frontiers in Ecology and Evolution, 2021 The South American native ungulates (SANUs) are usually overlooked in Eutherian phylogenetic studies. In the rare studies where they were included, the diversity of SANUs was underrated, keeping their evolutionary history poorly known.

Publicación Electrónica de la Asociación Paleontológica Argentina, 2017 South American native ungulates include several extinct lineages that evolved within the context of South American Cenozoic geographic isolation. By the late early Miocene Santacrucian Age, the orders Notoungulata, Litopterna, and Astrapotheria were ...

Cranial Morphology and Phylogenetic Relationships of Trigonostylops wortmani, an Eocene South American Native Ungulate [PDF]
Bulletin of the American Museum of Natural History, 2021 In 1933 George G. Simpson described a remarkably complete skull of Trigonostylops, an Eocene South American native ungulate (SANU) whose relationships were, in his mind, quite uncertain. Although some authorities, such as Florentino Ameghino and William B. Scott, thought that a case could be made for regarding Trigonostylops as an astrapothere, Simpson

The Neogene Record of Northern South American Native Ungulates [PDF]
Smithsonian Contributions to Paleobiology, 2018 South America was isolated during most of the Cenozoic, and it was home to an endemic fauna. The South American Native Ungulates (SANUs) exhibited high taxonomical, morphological, and ecological diversity and were widely distributed on the continent. However, most SANU fossil records come from high latitudes.

Collagen Sequence Analysis of the Extinct Giant Ground Sloths Lestodon and Megatherium. [PDF]
PLoS ONE, 2015 For over 200 years, fossils of bizarre extinct creatures have been described from the Americas that have ranged from giant ground sloths to the 'native' South American ungulates, groups of mammals that evolved in relative isolation on South America ...
