Microplankton from the Garden Cove formation, Campbell Island

Abstract

Three new species of fossil dinoflagellates, Deflandrea campbellensis, D. acutula, Svalbardella granulata, and one new acritarch species, Leiosphaeridia ovata, are described from the Garden Cove Mudstone of Campbell Island, 400 miles south of New Zealand. Several microplankton species previously described from other localities are listed. It is considered that the microplankton is Paleocene (Teurian) despite the occurrence of some Cretaceous elements, and that the depositional environment was near-shore or estuarine. The microflora is dominated by terrestrially derived microfossils, chiefly pollen. © Taylor & Francis Group, LLC.
