Abstract. CENOZOIC INVERTEBRATES OF ARGENTINA. The Cenozoic rocks of Argentina contain a rich, exceptionally
well preserved and remarkable diverse marine and continental invertebrate fauna. The main goal
of the present synthesis consists in revealing the continuous progress of the scientific research performed
during the last 50 years dealing with these assemblages. Initial studies of microfaunas were carried out between
the 50 and 60 and since then the interest for forams and ostracods experimented a marked increase
among workers. Analysis on these faunas not only improved the knowledge of their taxonomic composition,
provided a proper frame for biostratigraphic works for accurating age assignments of Argentinean
Cenozoic strata, but also became a new source of data to be used in paleoenvironmental interpretations.
Although known since the middle part of the XIX century, during the last five decades, macroinvertebrates
have been matter of a renewed interest by paleontologists. Being the most abundant, the Tertiary
marine shallow- water molluscs are the group that most noticeable drew the attention of researchers, and
a large part of the investigations focused to clarify systematic aspects that led to meaningful comparisons
with other Southern Hemisphere and Caribbean assemblages. Nevertheless, though a large amount of
work has been already done, these assemblages are in need of a comprehensive revision in order to accomplish
the proper information to make any final inferences involving origin of these faunas, as well as
their biogeographic and paleoclimatic implications. Several Tertiary groups (braquiopods, equinoids, bryozoans
and corals) still remains poorly understood, and only arthropods were subject of study by scientists
during this last decade. By the way, Cenozoic continental molluscs have been recently receiving attention
after that many years elapsed since the pioneer studies.
