Descripción
The distribution (time-space) of conchostracan across the Brazilian geological column is here analysed, and the potential application to the stratigraphical and paleogeographical correlations is proposed. The Jurassic-Cretaceous conchostracan faunas are briefly revised from the taxonomic point of view, including their problems, collecting problems and stratigraphical distribution. Such aim of the study is based on the faunal similarities, and also that there are many species in common across both periods. As previously reported by different authors, there are close relationships between Brazilian and Central African faunas, now tentatively extended to Venezuela and southern South America. Likewise, relationships between Chinese and West Gondwanan faunas are confirmed. Seven conchostracan assemblages based in their biochron are proposed and compared with the Jurassic-Cretaceous conchostracan assemblages from China and other regions
