Resumen:
In South America the extent of Silurian deposits is considerable. Acritarch assemblages have been reported from different basins: in Brazil from the Amazonas, Solimoes, Parnaiba and Parana basins (the latter also extended into Paraguay); in Bolivia from the Eastern Cordillera; in Argentina from the Sierras Subandinas, Chaco-paranense basin and the Precordillera.The purpose of this work is to point out the importance of the acritarchs, in addition to chitinozoa and miospores: firstly to appraise their biostratigraphic potential for Silurian sequences and secondly to provide new data about their paleoecological distribution and biogeography worldwide
