Abstract


Well preserved Mississippian palynological assemblages have been obtained from the
Cortaderas Formation in the Río Blanco Basin, northwestern Argentina. The geological setting and stratigraphic
provenance of the samples is provided. In this first part, fifty-two species are described from a total
of seventy-eight species of spores recognized. Five new species are proposed: Verrucosisporites incompositus
sp. nov., Verrucosisporites perbrevis sp. nov., Anapiculatisporites exiguus sp. nov., Anapiculatisporites
expolitus sp. nov. and Dibolisporites insolitus sp. nov. Previous worldwide geographic and stratigraphic
