A rich and varied miofloral assemblage consisting of Spores, Acritarchs and Chitinozoans is recovered from a sample belonging to the Poti Formation. Parnaiha Basin, Brazil. This assemblage is quite interesting in having characteristic palynomorphs like Verrucosisporites nitidus, Densosporites spitsbergensis, Vallatisporites vallatus, Dibolisporites microspicatus. Florinites guttatus, Hymenozonotriletes explanatus, Cirratriradites veeversii, etc. which suggest a stratigraphic range of Tournaisian-Visean to the sample under study. This is being reported first from the western border of this region while some palynological data exist regarding the eastern border In addition to this, this assemblage has a greater bearing in tackling the stratigraphic problems associated with these sediments. This also can help interpreting the geological data in a better fashion. A comparative study with other known Lower Carboniferous palynozones of Argentina, Australia, United States of America and Great Bretain is also attempted.
