A total of 58 productive samples have been palynologically analyzed from the upper Miocene and lowermost Pliocene of Ocean Drilling Program (ODP) Hole 646B in the central Labrador Sea. Pollen and spores are a major component of the assemblages and indicate a temperate-source vegetation, although they mainly comprise forms that are longranging in high latitudes. Reworking may account for some of these forms. A diverse marine palyno flora (70 taxa) was recovered, and five provisional dinocyst assemblage zones are erected. Palynomorph assemblages are thought to be largely allochthonous and may reflect changing bottom-water paleocurrents. The dinocyst flora consists of both oceanic and neritic species and indicates temperate surface-water conditions. Similarities exist with other dinocyst assemblages recorded from the northern North Atlantic and Norwegian Sea, although there are some important differences, including a diverse protoperidiniacean component at this site.Taxonomic Coverages
