Extract

The coral fauna of the Upper Mississippian (Chesterian) Pitkin Formation was described by Easton (1943) and, more recently, by Webb (1987), who defined two coral faunules. The lower faunule occurs throughout the Pitkin outcrop belt from northeastern Oklahoma to north-central Arkansas. The upper faunule has been recognized only in north-central Arkansas where a higher part of the Pitkin is preserved. Equivalent strata have apparently been removed to the west by the pre-Pennsylvanian regional unconformity that differentially truncates Chesterian strata across the Ozark uplift. Thus the upper faunule is less well known than the lower faunule. The purpose of this note is to describe a new tabulate coral from the upper faunule in Searcy County, Arkansas.
