Bergue, C.; Fauth, G.; Vieira, C. E.; Dos Santos, A.; Viviers, M. C. (2011). New species of Fossocytheridea Swain & Brown, 1964 (Ostracoda, Crustacea) in the Upper Cretaceous of Santos Basin, Brazil. Rev. bras. paleontol. 14(2): 149-156.
Eleven wells (1,765 cutting samples) from the Senonian of Santos Basin were examined, with the record of both marine and mixohaline ostracode faunas. The latter are composed mainly by Fossocytheridea and characterized by medium specific richness and high abundance. Four new species are here described: F. posterodentata, F. ventrotuberculata, F. santosensis and F. anfisulcata and another one is left in open nomenclature. Besides the conspicuous variability, F. ventrotuberculata sp. nov. is the first species described for the genus with valve reversal. The significance of these new species described and their potential for applied approaches are discussed.
