The Rich Fountain Formation was proposed in 1944 as the equivalent of the lower part of the Jefferson City Formation in a new Jefferson City Group. The Theodosia Formation was proposed as the equivalent of the upper Jefferson City and the lower portion of the overlying Cotter Formation.[1] This formation was also proposed for use in Arkansas by the original author of the name, but it was never used by other workers in Arkansas.
