ESTADO DA ARTE DAS PESQUISAS SOBRE OS BRAQUIÓPODES DO DEVONIANO BRASILEIRO

Abstract

State of the art of research on brachiopods from the Brazilian Devonian. During the Devonian, much of what is now the Brazilian territory was covered by seas and brachiopods were one of the most abundant phyla in these regions. The objective of this paper was to survey the state of the art of research on Devonian brachiopods found in the Paraná, Parecis, Amazonas, Parnaíba and Jatobá basins. To this end, a broad survey was carried out by reading articles, dissertations, theses, and abstracts in scientific events available both digitally and in print. The first Devonian brachiopods recorded in Brazil were in the Amazon Basin in the nineteenth century, while the Paraná Basin has the largest volume of taxonomic studies. However, in both basins there is still a need to review many taxa. In the Parnaíba Basin there is a notable lack of taxonomic descriptions of inarticulate brachiopods. Finally, studies on brachiopods in the Parecis and Jatobá Basins are extremely scarce, representing areas with great potential for new discoveries. The paleobiogeographic considerations made here are limited due to the need to review certain taxa, as mentioned above. Nevertheless, it is expected that this paper will serve as a basis for future taxonomic work and, consequently, the refinement of paleobiogeographic and paleoenvironmental inferences in the basins analyzed here.
