The biostratigraphic utility of the angiosperm pollen genus Pulcheripollenites is improved through the development of new biozones. Species of Pulcheripollenites, including one new species, P. sweetii, aid interpretations and correlations within three northern Canadian basins, in combination with additional new palynostratigraphic data and previously published biozonation schemes. Palynological assemblages recovered from the Bonnet Plume, Eagle Plain and Brackett basins determine relative ages and establish correlations with existing biozones that constrain intra- and interbasinal correlations for Upper Cretaceous and Paleogene strata. Strata from the upper Bonnet Plume Formation of the Bonnet Plume Basin range in age from the late Campanian to late Paleocene/early Eocene. The diverse assemblages recovered from the Bonnet Plume Basin contribute to paleogeographic and phytogeographic determinations and point to issues of diachroneity. Assemblages recovered from the Eagle Plain Basin were very impoverished ...
