“…In the last decades research on Cretaceous ostracods of Brazilian basins have received considerable attention, especially those in marginal marine environments. Their biostratigraphical potential in the South Atlantic was demonstrated recently in the revision by Fauth et al (2018). The Late Cretaceous ostracods from the Potiguar Basin were studied by Viviers (1995Viviers ( , 2000, Delicio et al (2000), Piovesan et al (2014a,b;2015a,b), andSantos Filho et al (2015), who improved significantly the knowledge on the evolution of this basin, and reinforced the correlation between Brazilian and North African ostracod faunas in the Upper Cretaceous.…”
