Description/Abstract Fifty-four species of spores, pollen, fungi, and algal palynomorphs were identified from the Vermillion Creek coal bed and associated strata, including underlying and overlying deposits and partings within the coal.^The stratigraphic distribution and relative abundances of these plant microfossils were determined in samples from three cores.^The palynomorph assemblage, which is late early Eocene in age, includes 8 species of pterophyte spores, 4 species of gymnosperm pollen, 39 species of angiosperm pollen, 2 species of algal coenobia or cysts, and 1 species of fungal spore.^The assemblage is dominated by the pollen species Platycarya paltycaryoides and Arecipites tenuiexinous.^Ten species appear to have biostratigraphic importance, based on their stratigraphic ranges in the Rocky Mountain region.^The record of their occurrence in a well-dated stratigraphic section is a contribution to Tertiary biostratigraphy in the central Rockies.^Palynologic evidence supplements stratigraphic, sedimentologic, geochemical, coal petrographic and other paleontologic evidence on the nature of the depositional environment.^The Vermillion Creek coal was deposited in a paludal environment adjacent to a nonsaline lacustrine system.^Evidence from botanical affinities of palynomorph species and habitats of living relatives indicates that the region had a moist subtropical climate in late early Eocene time.
