Late Cenozoic Fossil Mammals of Southern South America

In the last 30 years, taxonomic arrangements have been improved since many unpublished doctoral theses and scientific revisions have been done mainly in Argentina, Brazil and Uruguay. Scientific advances have allowed the discovery of new palaeontological sites where new fossil taxa have been found. The aim of this series is to update the systematic palaeontology of mammals registered in Late Miocene-Holocene sediments outcropping in southern South America (Argentina, southern Brazil, Uruguay, Chile, Bolivia and Paraguay), taking into account the progress made in the last 30 years.

Besides that, the update of the systematic palaeontology of mammals has allowed updates in biostratigraphic schemes. There is an increasing interest in developing biostratigraphic schemes for all mammal sequences in the world, to properly identify their stratigraphy that can be dated radiometrically, analysed magnetostratigraphically, and correlated as certainly and broadly as possible. This is especially true for the Late Miocene to Holocene times in the eastern Pampean region of Argentina, where an almost continuous biostratigraphic sequence constitutes the basis of the mammalian chronological scale of South America. In the last 30 years, the biostratigraphic resolution in the continental Cenozoic of South America has been increased in relation to previous scales.
