Abstract Smith, S.W., 1992: Microplankton from the Cape Lamb Member, Lopez de Bertodano Formation (Upper Cretaceous), Cape Lamb, Vega Island; In: Duane, A.M., Pirrie, D. and Riding, J.B. (eds.), 1992: Palynology of the James Ross Island Area, Antarctic Peninsula. Antarctic Science, Volume 4,No.3: 337-354 Special Issue, September 1992. Blackwell Scientific Publications Abstract: Samples from the lower Cape Lamb Member, Lopez de Bertodano Formation, Cape Lamb, Vega Island, Antarctic Peninsula have yielded rich and diverse marine palynofloral assemblages. The overall character of the palynofloral assemblages indicate a latest Campanian-earliest Maastrichtian age. Four new dinoflagellate cyst species Canninginopsis ordospinosa sp. nov., Microdinium ? gymnosuturum sp. nov., Phelodinium exilicornutum sp. nov. and Operculodinium radiculatum sp. nov. are described. Certain key dinoflagellate cyst taxa such as Operculodinium radiculatum sp. nov., Manumiella n. sp. 3 and Isabelidinium cretaceum allow a correlation of the lower Cape Lamb Member with the upper palynomorph zone 1/lower zone 2 on nearby Seymour Island.
