The presence of fossil animals (invertebrates and vertebrates) in sediments of the Bauru Group is quite common. Despite this fact, lhe pronounced endemism of the fau­ nas has not permitted, till now, the precise dating of the fossil-bearing levels. On the other hand, the occurrence of plants is much scarcer. In this context, the dis­ covery of a very wel1preserved microflora, at the Fazenda Nossa Senhora do Carmo, Sao Carlos Municipality, Sao Paulo States, deserves attention. This assemblage repre­ sents, in fact, the first record of palynomorphs in the Cretaceous of the Parana Basin. Study of the very diversified material, including several stratigraphical1y important species, has allowed the attribution of a Coniacian age for the fossiliferous strata. It has also been possible to drawn important stratigraphic, paleoecological, paleoclimatologi­ cal and tectonic conclusions regarding the studied outcrop.
