Abstract

Spore and pollen assemblages occurring in a pillar column of the Upper Pennsylvanian Redstone coal seam of West Virginia are used to interpret the phytoecological history of the ancient swamp in which the source material of the coal was deposited. Punctatosporites minutus and other bilaterally symmetrical monolete spore species predominate throughout the thickness of the seam and mask the vertical variation of other apparently more significant species. With the removal of P. minutus from the count, additional assemblages could be recognized, some of which correspond closely to variations in the maceral content of the seam. As a result, three phases in the ecological development of the Redstone coal were distinguished. Forty-nine sporomorph species, placed in 34 genera, were recognized. Ten species and one genus, Stripites, are described as new. Pollen grains attributed to the Chlamydospermae, Hamiapollenites and Vittatina, more typical of Permian assemblages, are recorded from the lower portions of the seam, and are considered to have been contributed from extra-swamp sources. Densosporites and Cristatisporites are reported for the first time from an Upper Pennsylvanian coal seam in the United States.
