Resumen:
Abstract. In this report, we analyze the angiosperm fossil record (micro- and
megafossil) from the central and southern basins of Argentina, southern South
America, deposited between the Late Barremian (128.3 Ma) to the end of the
Coniacian (85.8 Ma). Based on this analysis, three major stages in the evolution
of the angiosperms in the southernmost region of South America are established
as follows: the Late Barremian-Aptian, the latest Aptian-earliest Albian, and
the Middle Albian- Coniacian. The comparison between our fossil data set and
those from Australia, North America, Asia and Europe suggest that the evolution
and diversification of the angiosperms at mid and high latitudes in both
hemispheres occurred roughly synchronously.
