dc.description.abstract The Upper Pennsylvanian (Conemaugh Group) Duquesne Coal west of Steubenville, Ohio represents a deltaic peat-accumulating swamp, and is one of the best known of coal swamp floras. In a few places, the peat was infiltrated and permineralized by calcium carbonate prior to coalification, thus producing coal balls in which both morphological and anatomical structure of the constituent plant parts are preserved. The plant material represents primarily the community that inhabited the peat-accumulating environment, but some remains from near-swamp environments also are represented. The flora is relatively diverse, consisting of over 55 megafossil taxa of isolated organs that were produced by at least 25 species of plants. All five major groups of Pennsylvanian coal-swamp plants (i.e., Lycopsida, Sphenopsida, Pteridopsida, Pteridospermopsida and Cordaitales) are represented. en_US
