Shale samples from three Upper Pennsylvanian mine assemblages overlying the Danville Coal Member (VII) were analyzed and compared with respect to miospore content. The palynoflora from twenty seven sites (nine per assemblage) were found to contain 108 species assigned to 40 genera. A comparison of the palynoflora from the three mines reveals 17 genera and 32 species found in common. The palynoflora was dominated by the following four genera: Lycospora, Laevigatosporites, Punctatisoprites, and Puntatosporites. Genera of secondary importance include: Spinosporites, Crassispora, Calamospora, Latosproites, Cyclogranisporites, and Thymospora. Abundance data from the three localities were analyzed using cluster analysis. Results indicate few taxonomic differences within or between mines. Data from the three localities show an abundance of arborescent lycopods, ferns, and sphenopsids with few gymnosperms. This is suggestive of current paleoenvironmental models which indicate a wet swamp regime.
