Article: Palynology of the Springer Formation of southern Oklahoma, U.S.A.

Twenty-three surface samples were studied from the Springer formation at its exposure in Johnston County, Oklahoma. The Springer formation is of interest because of the commercial occurrence of oil and gas in its subsurface sandstones, but there has been wide disagreement as to its correct age. The microflora is transitional in character with Mississippian and Pennsylvanian spores represented, and it is regarded as a transgressional facies from the Mississippian Goddard formation to the Pennsylvanian Morrow formation in the area studied. The systematic description of 104 microspore species is included in this paper. Seven new genera and thirty-five new species are proposed. One new name combination is suggested. The new genera represented are Costatascyclus, Cystoptychus, Hadrohercos, Nexuosisporites, Tantillus, Trochospora, and Scutulum. The remaining sixty-nine species are referable to previously described taxa and include representatives with ranges from Tournaisian to Westphalian B in terms of European nomenclature. By North American nomenclature the range would be from Kinderhook to Atokan.
