A composite columnar section from the upper and middle(?) Reedsville in south- central Pennsylvania showing the stratigraphic-faunal separation of brachiopod provinces I and IL See Figure 14 for geographic extent of this overlap. stratigraphic succession of the faunas follows a pattern whereby the linguloids overlie the rhynchonellids (Fig. 15). Brachiopod province III, dominated by orthids and spiriferids, broadly overlaps province II in southwestern Virginia, but there is no marked stratigraphic separation of the faunas. In the southern part of the mixed zone the linguloids of province II disappear suddenly, but Orthorhynchula linneyi is gradu- ally outnumbered by Hehertella sinuata. The two dominant species of brachiopod.
