Sites 1165 and 1167 were drilled on the continental slope and rise seaward of Prydz Bay, East Antarctica. The sediments penetrated are glacigene and independently dated as Neogene age (early Miocene and younger) using diatoms, radiolarians, nannofossils, and paleomagnetic data. In this depositional setting, most, though not all, palynomorphs recovered are not in situ but have been recycled from older sequences.However, a number of dinoflagellate cyst taxa recovered from Site 1165 support a Neogene age, although their stratigraphic distribution requires further study. They include species referable to the genera Batiacasphaera, Protoellipsodinium, cf. Cymatiosphaera, and Svalbardella. Fossil pollen and spores recovered from Site 1165 include a spore species that appears to be diagnostic of early Miocene sediments encountered in the Cape Roberts Project drill hole CRP-1 in the Ross Sea. The presence of this species, referred to as Coptospora sp. b, strengthens the case that some other spore and pollen species ... : Supplement to: Mcphail, Michael K; Truswell, Elizabeth M (2004): Palynology of Neogene slope and rise deposits from ODP Sites 1165 and 1167, East Antarctica.
