Summary:

Kenneth limestone is upper part (brachiopod-bearing beds) of Kokomo limestone of Foerste (1904). Thickness a few ft at Kokomo to over 35 ft near type section. Fossils listed. Fauna has Cayugan affinities but much work is needed to establish its correlation.

Summary:

The Kenneth Limestone Member of the Wabash Formation is light-colored dense to fine-grained bedded to massive cherty limestone that is typically exposed in an abandoned France Stone Co. quarry near Kenneth. According to Pinsak and Shaver, the Kenneth type section is in the large composite quarry in the center of sec. 30, T27N, R1E. Some question remains as to the actual type section designated by Cumings and Shrock, as in 1928, they also mentioned quarrying in the adjoining section (sec. 25, T27N, R1W). The unit appears to be coarsely mottled in places and in some other places consists of whitish to pinkish granular limestone that commonly is abundantly fossiliferous. This facies includes coquinas of brachiopods and ranges to reef-framework rock with abundant coral. The Kenneth has very limited distribution. Its basic character as cherty dolomitic limestone and its high stratigraphic position hardly distinguish the Kenneth from the similar Liston Creek. It is distinguished only where Silurian rocks of its type are underlain by the distinctively laminated Kokomo Member. The upper Kenneth contact everywhere coincides with the pre-Middle Devonian unconformity. It is now known only in Cass, Miami, and Carroll Cos. It ranges in thickness from an erosional zero to an average of 25 to 30 ft and attains a maximum of about 45 ft. Within the Wabash, the Kenneth correlates with the upper part of the Liston Creek and with the upper part of the Bailey Limestone of the Illinois basin. Conodont and ostracod evidence indicates a very late Silurian age.
