description |
The Tatuí Formation, one of the Brazilian Paraná Basin geological units, is developed solely in the State of São Paulo, southeast Brazil. It is studied herein, through outcrops at the eastern border of the basin, which are siltstones and fine sandstones, interbedded with some coarse and conglomeratic sandstones. Published papers on its fossils are sparse, dealing with some groups but not involving the entire association. This paper deals with ichnofossils, arthropods (conchostracans, isopods, and indeterminate crustaceans), plants (pteridophytes and spermatophytes) and fish remains (scales and teeth of Actinopterygii and Sarcopterygii). Foraminifers and sponge spicules were reported in short communications without illustrations and from uncertain stratigraphic positions. The Tatuí Formation paleoenvironmental deposition evolved through three phases. The first contains only the euryhaline fossils in siltstone beds. The second phase is regressive, with continental fossils (conchostracans and plants) in massive or laminated siltstone beds and conglomerates. The third stage is transgressive with hummocky cross – stratification in sandstone and increasing salinity. La Formación Tatuí (Pérmico Temprano, Cuenca del Paraná), Brasil: Consideraciones paleontológicas y paleoambientales ResumenLa Formación Tatuí es una unidad litoestratigráfica de la Cuenca del Paraná que aflora exclusivamente en el Estado de São Paulo, Brasil. En su borde nororiental está formada por limolitas y areniscas finas que poseen intercalaciones de areniscas gruesas y conglomeráticas. Este trabajo caracterizó en esta formación diversas evidencias de fósiles: huellas, artrópodos (conchostracos, crustáceos isópodos e indeterminados), vegetales (helechos y fanerógamas) y restos de vertebrados (escamas y dientes de Actinopterygii y Sarcopterygii). Foraminíferos y espículas de esponjas fueron reportados en comunicaciones breves, entretanto, sin estar acompañado de ilustraciones y de sus posiciones estratigráficas. Tres fases de deposición permiten reconstruir el paleoambiente de la Formación Tatuí. En la primera fase hay presencia solamente de fósiles eurihalinas en limolitas. En la segunda fase, fósiles continentales (conchostracos y vegetales) que están presentes en camadas limolíticas masivas o laminadas y en conglomerados vinculados a una etapa regresiva. Finalmente, la tercera fase se caracteriza por una etapa transgresiva con la presencia de estratificación cruzada “hummocky” y aumento de la salinidad. |
