Diverse assemblages of well preserved miospores and microplankton have been obtained from a series of samples collected across the boundary between the Bedford Shale and Berea Sandstone Formations in central Ohio. The miospores indicate a Late Devonian (pre-Carboniferous Tournaisian)* age for each of the samples. The microplankton support this age determination. A number of microplankton species not previously recorded from North America are present.
