PALINOLOGÍA DE LA FORMACIÓN EL IMPERIAL, PALEOZOICO SUPERIOR, CUENCA SAN RAFAEL, ARGENTINA. PARTE 1:ESPORAS
AbstractThe microfloristic study of the El Imperial Formation, Upper Paleozoic of San Rafael Basin is presented. A diversified microfloristic assemblage including spores, pollen grains, incertae sedis and acritarchs has been recognized. This contribution comprises information concerning the geological setting and the systematic description of the spores. Forty-one species of microspores and three species of megaspores have been quoted. Twenty-nine previously described taxa have been cited. Three species: Verrucosisporites andersonii (Anderson) Backhouse, Horriditriletes curvibaculosus Bharadwaj and Salhuja and Grandispora maculosa Playford and Helby have been described in Argentina for the first time. Twelve species have been designated informally because of their numerical insufficiency.
