Paleogene Land Mammal Faunas of South America; a Response to Global Climatic Changes and Indigenous Floral Diversity
In addition to being composed of essentially different groups of mammals, those of the South American continent seem to have responded to the climatic changes associated with the ECCO and subsequent conditions in a pattern that was initially comparable to, but subsequently different from, their North American counterparts.
Eocene primates of South America and the African origins of New World monkeys
The platyrrhine primates, or New World monkeys, are immigrant mammals whose fossil record comes from Tertiary and Quaternary sediments of South America and the Caribbean Greater Antilles. The time

Paleogene land mammal faunas of South America
Persistence of a Mesozoic, non-therian mammalian lineage (Gondwanatheria) in the mid-Paleogene of Patagonia
The new taxon adds evidence regarding the extensive radiation of the Gondwanatheria throughout the Southern Hemisphere, persistence of several lineages well after the Cretaceous/Paleogene boundary, and early evolution of hypsodont types among South American herbivorous mammals.
New Early Eocene Mammalian Fauna from Western Patagonia, Argentina
It is concluded that the two new fossil mammal localities from central-western Patagonia are part of a possible new biochronological unit, but the formal proposal of a new SALMA awaits completion of taxonomic analysis of the materials reported upon here.
Neolicaphrium recens frenguelli, 1921, the only surviving proterotheriidae (Litopterna, Mammalia) into the South American Pleistocene
The litoptern Proterotheriidae are extinct endemic South American ungulates frequently used as an example of evolutionary convergence with the horses. They were considered to be exclusively Tertiary
