Last 3 pages of mimeographed program of a conference on correlation of the Pennsylvanian System of the Ardmore basin, held May 5, 1936. At base of the Pumpkin Creek south of Ardmore, nodular white dense limestone varying in thickness from 1 to 10 feet or more. Limestone contains an undescribed species of FUSULINA which also occurs 50 feet below top of the Atoka in the so-called Red Oak member. Name Frensley is here proposed for this limestone and the shale overlying it and beneath the overlying prominent sandstone. Frensley marks top of the Atoka or Red Oak of eastern Oklahoma.
Well exposed on Frensley Farm, in SE/4 sec. 30, T. 3 S., R. 2 E., Carter Co., eastern OK.
