A NEW CAMPANIAN DINOFLAGELLATE CYST FROM ANTARCTICA: A BIOSTRATIGRAPHIC AND PALEOECOLOGICAL KEY SPECIES
Palynological analysis of Upper Cretaceous marine rocks from the Rabot and Snow Hill Island formations, James Ross Basin, northeastern Antarctic Peninsula, has revealed the record of a previously undescribed dinoflagellate cyst species, previously assigned to Oligosphaeridium sp. A. Here, we provide...

The new species is found in Campanian strata, which are calibrated with magnetostratigraphic data. It is considered an important Late Cretaceous biostratigraphic marker commonly recorded in offshore environments of Antarctica.
