Macphail2 and E.M. Truswell3 ABSTRACT Twenty-three core catcher samples from Site 1166 (Hole 1166A) in Prydz Bay were analyzed for their palynomorph content, with the aims of determining the ages of the sequence penetrated, providing informa- tion on the vegetation of the Antarctic continent at this time, and determining the environments under which deposition occurred. Di- nocysts, pollen and spores, and foraminiferal test linings were recov- ered from most samples in the interval from 142.5 to 362.03 meters below seafloor (mbsf). The interval from 142.5 to 258.72 mbsf yielded 1Macphail, M.K., and Truswell, E.M., palynomorphs indicative of a middle–late Eocene age, equivalent to the 2004.
