Summary:

Pg. 262-263, chart 2 (column 51). Auburn chert. Placed in lowest Trentonian to conform to placement of Spechts Ferry shale with which it is correlated. [Age is Middle Ordovician.]

Cooper, G.A., 1956, Chazyan and related brachiopods [U.S.-Canada]: Smithsonian Miscellaneous Collections, v. 127, pt. 1, 1245 p.


Summary:

Pg. 117. Auburn chert. Has been suggested that Auburn chert be included in Plattin group, but brachiopods are not in accord with this suggestion. Presence of RAFINESQUINA indicates a higher correlation. Here suggested that formation may be chertified Decorah of Missouri, =Barnhart formation (new), rather than Plattin and correlation should be with Guttenberg member of Decorah. [Age is Middle Ordovician (Trentonian of Twenhofel and others, 1954, GSA Bull., v. 65, p. 247-298).]
