The Ostracod genus Majungaella Grekoff in Argentina

The Ostracod genus Majungaella Grekoff in Argentina

ABSTRACT The status of the Upper Jurassic and Cretaceous progonocytherid ostracod Majungaella, which is strictly gondwanine in its distribution, is reviewed in respect of its presence in Argentina where it is shown to be restricted to Patagonia. Of the seven species recorded in Argentina, M. pavta sp. nov., M. sp. and M. australis Rossi de García and Proserpio seem to be restricted to southern South America. Four species, however, are of much wider occurrence: M. santacruziana (Rossi de García) also occurs in Australia and M. hemigymnae Brenner and Oertli, M. praehemigymnae Valicenti and Stephens and M. nematis Grekoff, all originally described from southern Africa or Madagascar, are described from Argentina for the first time. The implications for intercontinental correlation and the reconstruction of palaeo-migration routes are discussed.
