dc.description.abstractPERMINERALIZED STEMS OF TIETEA AND PSARONIUS OF THE PARANÁ BASIN, CORUMBATAÍFORMATION, PERMIAN. Silica permineralized stem fragments from six municipalities of São Paulo, Brazil, belonging to the Passa Dois Group, Corumbataí Formation (Guadalupian, Permian), were analysed. Morpho-anatomic characteristics of the stems and steles, observed on petrographic slides or polished sections, have permitted the classification of many specimens as Tietea cf. Tietea singularis. A stem piece from the region of Casa Branca, determined as Psaronius cf. Psaronius arrojadoi, corresponds to the first true record of this genus in the Paraná Basin. A generic/specific identification was not possible for radicular mantle samples having no preserved steles. Despite the strong influence of taphonomic factors on the record, all known Marattiales fossils from the Paraná Basin in Brazil present relatively small steles and meristeles, and that may be related to hydric stress. Taphonomic, paleoecological and biogeographical aspects of the analysed fossils are discussed as well.en
