Occurrences of Devonian ostracods in the Paraná basin were mentioned by Lange (1943, 1954) and Lange & Petri (1976). Therefore, the first publication of ostracods from Brazilian Paleozoic strata was reported by I. D. Pinto e I. Puper, which studied samples from Ponta Grossa Formation, Paraná State, S-Brazil (Pinto & Puper, 1986). These authors proposed a new species of marine ostracod Lapazites roesleri Pinto & Puper, 1986 and based on these occurrences a neritic zone of a shallow sea palaeoenvironment was interpreted. Is important to emphasize that Lapazites roesleri, was the first formally proposed ostracod species to Brazilian Paleozoic strata. The other two publications about Brazilian Paleozoic ostracods were published also in 19th century (Maranhão & Petri; 1996; Sonh & Rocha-Campos, 1990). These two articles are about Permian ostracods from Brazil, and both refer to Corumbataí Formation. Sohn & Rocha-Campos (1990) identi fied five groups of limnic ostracods from Corumbataí Formation: Cypridopsis? spp., Candona sp., Candona? sp, Gutskhickia? sp. and Darwinula? spp. Based in previous articles dealing with palaeoenviroment of Corumbataí Formation and on recorded of limnic ostracods, Soh & Rocha-Campos (op.cit.), the depositional system was interpreted influenced by river influx in a shallow marine intertidal and lagoonal environments. Maranhão & Petri (1996) identified occurrences of ostracods but, it is all left in open nomenclature for genus and species level.
