Summary:

Authors follow usage of Gardner (1974) who divided the Dundee into (ascending) Reed City Member and Rogers City Member. [Reed City has never been formally proposed and is therefore considered informal by the GNU.] The Rogers City is lithologically and paleontologically similar to the coeval subunit II of the Thiensville Formation of WI. The Reed City is not wholly equivalent to subunits I and III of the Thiensville, but was deposited under similar environmental conditions. The Reed City is restricted to the western part of the basin.
