Samples from four drill sites in Prydz Bay, East Antarctica, were examined with the aim of determining the age of the oldest lithological units penetrated at each site. Lithological considerations have made age assessment difficult; most samples are diamictites, and contain several generations of pollen and spores which have been recycled from older deposits by glacial processes. Palynomorphs identified fall into three major groups; Permian spores and pollen, Cretaceous and Tertiary spores and pollen, and early Tertiary dinoflagellates. At Site 740, where reddish and green sandstones and siltstones represent the oldest part of the drilled sequence, recovery of palynomorphs was too sparse to resolve the age of this unit. At Site 741, grey sandstones and siltstones at the sampled base yielded an abundance of Early Cretaceous, probably Albian, spores and pollen; there is little evidence for a recycled origin. At Site 742, the oldest sampled section yielded depauperate spore and pollen floras which are possibly Late Cretaceous in age, although rare Eocene dinoflagellates are present. Basal sediments at Site 739 are diamictites which contain sparse, apparently recycled floras, and must be as young as Eocene or Oligocene.
