Small spore taxa from throughout the vertical extent of Dunkard strata are listed in stratigraphic sequence. It is concluded that the occurrences of <em>Triquitrites</em>, the culmination of monolete spore genera, the limited appearance of bisaccate, striate pollen, and the continuing occurrence of numerous Pennsylvanian trilete spores are positive evidence for assigning a Pennsylvanian age to the Dunkard.
