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 s...
