Dating Age In Prairie Du Chien
For many years the Prairie du Chien has been treated as a group and the Shakopee, New Richmond, and Oneota as formations. The Shakopee and New Richmond were for a time classified by the USGS as Lower Ordovician (Beekmantown) and Oneota dolomite (formerly classified as Lower Ordovician) was classified as Cambrian or Ordovician, it being assigned by E.O. Ulrich to his Ozarkian system. A.C. Trowbridge and G.I. Atwater (GSA Bull., v. 45, p. 78-79, 1934) would include all of Prairie du Chien group in Lower Ordovician, and it is so classified in the Report of the 9th Annual Field Conference of the Kansas Geological Society (1935) and by the USGS.
