Plant microfossils from the Burrard Formation of western British Columbia

Spores, pollen grains, and other plant microfossils from the Burrard Formation [Tertiary] underlying the City of Vancouver are described and illustrated. The microflora contains a predominance of ferns and angiosperms, with minor gymnosperm and fungal components. The paleoecology of the sediments is assessed in terms of probable climate, topography, and mode of deposition. Comparisons with other micro- and macrofloras suggest that Upper Cretaceous and middle Eocene ages are both represented within the rock formation.
