Abstract
Fourteen samples from three surface sections of the lowermost Columbus Limestone in central Ohio yielded small collections of stratigraphically diagnostic conodonts. The sequence of the conodonts in the strata studied is similar to that previously reported from the eastern United States. The presence of Icriodus huddlei huddlei Klapper & Ziegler confirms the stratigraphic placement of the basal sandstone of the Madison Quarry section as Devonian and correlative to the Lower Columbus Limestone.
