Waagen's lithostratigraphic subdivision was used almost for one century until Kummel and Teichert and associates in 1960's redefined the litho stratigraphy of the Salt Range and Surghar Ranges in terms of modern stratigraphic nomenclature practices as well as piloted a detailed paleontological study of the rich Late Permian and Early Triassic faunas; such as brachiopods, Ammonites, conodonts, bivalves, fusulinids, etc.
The objectives of our investigation of the conodonts of the Desmoinesian Bucktown Coal Member of the Dugger Formation in the eastern part of the Illinois Basin in Indiana included describing the conodonts, furthering the development of a stable Pennsylvanian conodont taxonomy, interpreting paleonvironments, and continuing the establishment of regional correlations in the Midwest.

We have undertaken a study of conodonts in the Viivikonna Formation with several objectives: to discover if this specific facies harboured an environmentally distinctive conodont fauna; to determine if the collections from different lithologies were dominated by different taxa; and to refine the biostratigraphy of the formation, especially through determination of the position of the base of the Amorphognathus tvaerensis Zone.
