Quantitative analysis and paleoecology of the Secor Coal and roof-shale floras (middle Pennsylvania, Oklahoma)

The Secor Coal of Oklahoma (Boggy Formation, lower Desmoinesian/Westphalian D equivalent) is one of the few coals discovered, to date, in which Anabathra pulcherrima (=Paralycopodites brevifolius) was a dominant element. Anabathra and Lepidophloios define the major assemblages in the coal, which also contains elements of medullosan pteridosperms and Cardiocarpus spinatus producing cordaites. The Lepidophloios to Medullosa gradient is not obscured by the numerous Anabathra-dominated zones, and a disturbance element is suggested in association with Anabathra abundance. Comparison of the coal-ball flora with a clastic-compression flora from the roof of the coal reveals widely divergent patterns of dominance and diversity. The compression flora is strongly dominated by medullosan pteridosperms with subdominant marattialean tree ferns. As in most instances, the compression flora from the immediate roof of the coal is not an accurate representation of the peat-forming vegetation, at either the level of species composition or the relative abundance of major groups of plants. The swamp and surrounding clastic deltaic environments were edaphically distinct and supported separate floras between which there was limited species exchange.
