The microfloristic assemblagesinclude miospores, incertae sedis and acritarchs. Information about the geological setting and the systematics of the spores is given. Thirty-nine species of microspores are mentioned. One new species, Verrucosisporites cordubensis is pro po sed herein. Eight species: Calamospora plicata (Luber y Waltz) Hart, Retusotriletes simplex Naumova, Brevitriletes levis (Balme y Hennelly) Bharadwaj y Srivastava, Horriditriletes tereteanglatus (Balrne y Hennelly) Backhouse, Verrucosisporites trisecatus Balme y Hennelly, Dictyotriletes aules Rigby y Hekel, Secarisporites lacunatus (Tiwari) Backhouse y Punctatosporites't sp. are cited for the first time frorn Argentina.
