Implications for high latitude gondwanide palaeozoogeographical studies of some new Upper Cretaceous marine ostracod faunas from New Zealand and the Antarctic Peninsula
Sixty species of Ostracoda have been recovered from Cenomanian, Santonian and Maastrichtian strata in New Zealand, and late Campanian sediments on Snow Hill and James Ross islands in the Antarctic Peninsula. The two main New Zealand sites are in latest Maastrichtian strata, but in contrasting therma...
