The Caney, Goddard, and Springer Formations of the Ardmore, Oklahoma region have been variously assigned to Mississippian and Pennsylvanian ages. Invertebrate fossil studies have not been in entire agreement, therefore an attempt has been made to determine the ages of these formations by palynological assemblages. Comparative studies of the fossil spores in the three Oklahoma formations with Lower Carboniferous assemblages from Great Britain, Spitzbergen, and Russia indicate that the Caney, Goddard, and Springer units have considerable palynological similarity with Visean and Namurian A.
