Abstract

Late Pennsylvanian and early Permian rocks, exposed in central Oklahoma, contain facies changes, fossils, pebbles, cross-bedding, and other diagnostic features which permit a paleogeographic map to be drawn for the area. It is recognized that the sea, throughout much of the area, was shallow (zero to perhaps 200 ft. deep), and that the sea floor was almost without relief. It is, therefore, obvious that the strand line may have oscillated widely. Nevertheless, agreement among the various bits of evidence is good enough that representative shoreline positions and orientations can be drawn. The sea indicated on the map appears to have withdrawn in an approximately northwesterly direction.
