Stratigraphic, lithologic, faunal and condont biozone analysis will provide insight to whether or not East Liberty Bone Bed, in Logan County, Ohio, and Little Hardwick Creek Bone Bed C, in Vaughns Mill, Kentucky, are chronostratigraphic correlations to one another; they are separated by 370 kilometers (230 miles). Material from each bed was collected and broken down in acid and analyzed. Remaining residue after acid treatment was analyzed under a dissecting microscope for lithological and fossil contents, identified from previous fossil vertebrate findings at other locations.
Final analysis of these beds showed that lithologically and faunally they are very similar. However, conodonts observed in the beds placed East Liberty Bone Bed within the linguiformis conodont biozone (376-376.5 ma) and Little Hardwick Creek Bone Bed C within the triangularis conodont biozone (374-376 ma). Therefore, East Liberty Bone Bed and Little Hardwick Creek Bone Bed C do not chronostratigraphically correlate to one another. To determine if there is a chronostratigraphic correlation between East Liberty and Little Hardwick Creek, future studies should focus on bone beds A and B at Little Hardwick Creek to determine if there is a chronostratigraphic correlation between East Liberty Bone Bed and Bone Beds A and B at Little Hardwick Creek.
