Title: Conodonts and stratigraphy of the Olentangy shale (middle and upper Devonian), central and south-central Ohio
Author: Gable, Kristine Marie
Description: Ninety-two samples of Olentangy Shale, collected from seven surface sections in central and south-central Ohio, yielded 13,480 identifiable conodont elements, which are assigned to the apparatuses of eight Middle and Upper Devonian multielement species. The lower Olentangy Shale contains few diagnostic conodonts, and correlation with either the Tully Formation (upper Givetian) or the Hamilton Group (upper Eifelian to upper Givetian) of New York is plausible. The upper Olentangy Shale lies mainly within the middle Palmatolepis triangularis and the lower crepida zones, is uppermost Frasnian and lower Famennian in age, and is correlatable with part of the Sweetland Creek Shale of Iowa, the Hanover Shale of New York, and the Dunkirk Shale Member of the Perrysburg Formation of New York.
