The Dunkard Group of the Appalachian basin, Ohio–Pennsylvania–West Virginia, is a > 340 m thick sequence of primarily fluvial and lacustrine deposits that contain a diverse fossil record including a blattoid insect forewing identified asSysciophlebia balteata(Scudder). This wing originates from the Cassville Shale in the Waynesburg Formation, at the very base of the Dunkard Group.S. balteatais a zone species of a Late Paleozoic spiloblattinid insect zonation that is calibrated by the co-occurrence of spiloblattinid zone species with conodont- and fusulinid-zone species in Kasimovian to Early Asselian mixed marine-continental profiles of New Mexico, USA, and the Donets basin in the Ukraine, as well as by the isotopic ages of volcanic intrusions into the Late Stephanian (Gzhelian) strata of the Saale basin in Germany. The base of the zone underlying theS. balteataZone is defined by the FAD ofSysciophlebia ilfeldensisin the Late Gzhelian, and has an upper limit (LAD) of Early to Middle Asselian. An Early or Middle Asselian to earliest Sakmarian range of both the subzones of theS. balteataZone can be inferred. Given that the mean duration of a spiloblattinid insect zone is about 1.5 to 2 Ma, the upper limit of theS. balteataZone is Early Sakmarian. Hence, the base of the Dunkard Group should be maximally of Early Asselian or minimally of earliest Sakmarian age.
