In the last 50 years, several causes contributed to increase the knowledge of Paleogene continental mammals in Argentina. Among them, the efforts focused in prospecting new localities, the increasing amount of researchers and the application of new techniques are the most important. The interest of paleontologists in these subjects is reflected in the publication of numerous articles with different approaches. The discovery of new land-mammal bearing localities outside the classical Patagonia, like those from the northwest and central Argentina, and the Antarctic Peninsula, provided a large number of fossils that allowed the recognition of new taxa. On this basis, many phylogenetic, paleobiogeographic, paleobiologic, and taphonomic studies could be carried out. Geologic, radiometric and magnetostratigraphic studies helped improving the calibration of land-mammal bearing horizons and correlation among basins. In this brief contributionthe main progresses in the above mentioned subjects are summarized.
