The primary purpose of the present study has been to establish palynological evidence on the geological age of the Dunkard strata, a subject of debate for at least 90 years. During this time the popular inclination has been to accept the age as Permian without serious question. The present study of fossil spores and pollen substantiates an Upper Pennsylvanian rather than a Permian age for the entire sequence of strata called the Dunkard Group.
