Abstract
The main goal of this research Project is to seek funds to allow Dr. ARTURO CÉSAR TABOADA, CONICET, Argentina, to come to Brazil to interact with members of our research group in the study of Late Paleozoic brachiopods of the Parana Basin. Dr. ARTURO is a leading scientist in Late Paleozoic brachiopods of Gondwana, and is interested in coeval Brazilian material. If approved the project will be developed through the detailed taxonomic identification of the species found in rocks of the Itararé Group, Paraná Basin, Brazil, Mafra and Taciba (=Rio do Sul) formations. Although many specimens of these units are already available to study, which are amassed in some scientific collections (IBB/UNESP, SP, and CENPALEO), new material will be sampled as well. We also intent to do detailed comparisons with Late Paleozoic forms of the Argentina and Australia. The project seeks to revise the available taxonomic identification of brachiopods of the Itararé Group (many of them only recorded in taxonomic lists). The goal is to establishes well constrained biostratigraphic correlations with the Argentinean basins, such as those recently proposed by Neves et al. (2014a, b), on the basis of fossil bivalves. As discussed in the scope of the FAPESP project 13/25317-7, "Late Paleozoic marine invertebrate assemblages in Gondwanian basins of South America, especially in Brazil, are characterized by the presence of brachiopods, bivalves, gastropods and echinoderms, among others. Brachiopods of the Permian succession of the Parana Basin have restrict vertical and horizontal distribution, but even in this context they are key elements to biocorrelations with other late Paleozoic marine deposits of South America and Australia. The age and affinities of the marine invertebrate assemblages in such countries are better constrained with international biostratigraphical schemes. Notably, six decades after the first mention of the brachiopods in the literature of the Itararé Group they still known only by references that appear in taxonomic lists. Despite of that there are several interesting questions to be answered, as follow: A- What are the affinities and age of those brachiopods? B- Why some deposits record bivalve-rich assemblages (Teixeira Soares) and others only brachiopod-rich concentrations (Mafra, Butiá quarry)? C- Are there differences in age and paleoecology among those assemblages? In this project, we will address the systematics, paleoecology and stratigraphy of those brachiopod-rich assemblages of the upper portion of the Itararé Group, Mafra and Taciba formations (Asselian), as a crucial step to better constrain the age, paleobiogeographical affinities andbiocorrelations of those marine invertebrate assemblages that were tied to de demisse of the late Paleozoic glaciation in Paraná Basin, trying to answer the issues highlighted above."
