(1965) | El Reno - Duncan | "The beds lie only a few feet above the contact of the Hennessey and are Duncan rather than Chickasha." beds are "older than the Chickasha"\nThe El Reno Group is the stratigraphic equivalent of the Pease River Group of North Texas. The Duncan Sandstone is the lowermost Formation of the El Reno and hence is Kungurian, probably Roadian in age. (see e. g.
