Two new members of the Howard Limestone Formation of the Wabaunsee Group have been named -the Wauneta Limestone Member and the Shangai Creek Shale Member. The type section is designated along U.S. Highway 166 in Chautauqua County about 71/2 miles east of Cedar Vale in sec. 7, T.34 S., R. 10 E. The units are important in understanding the development of Virgilian (Pennsylvanian) cyclothems. A limestone unit has been recognized, but unnamed, in the Howard Limestone Formation for many years. The unit is present in the southern part of the State in Greenwood, Elk, and Chautauqua Counties. Because of the importance in the understanding of the Virgilian cyclothems, it is deemed appropriate to name and describe the unit formally as the Wauneta Limestone Member of the Howard Formation. The Wauneta Limestone Member overlies the Aarde Shale (restricted) and underlies the Shangai Creek Shale (new name) as part of the Howard Limestone Formation of the Wabaunsee Group (Virgilian, Upper Pennsylvanian). Units of the Howard Limestone consist of (from oldest to youngest): Bachelor Creek Limestone, Aarde Shale with the Nodaway Coal Bed, Wauneta Limestone, Shangai Creek Shale, Church Limestone, Winzeler Shale, and Utopia Limestone. The Howard Formation is underlain by the Severy Shale and overlain by the White Cloud Shale Member of the Scranton Shale (Fig. 1). The Severy Shale is a silty, micaceous, light-gray shale with thin beds of sandstone. Locally, the sandstones are ripplemarked and may contain softsediment deformation features. Nodules may be present as well as tracks, trails, and burrows. Thickness ranges from 60 to 80 feet (White, 1987). Conformably overlying the Severy is the basal unit of the Howard, the Bachelor Creek Limestone, which is a gray, silty, fossiliferous limestone. Fossils include a few fusulinids, brachiopods, bryozoans, crinoid fragments, echinoid plates and spines, and clams; burrows may be present. The unit is from 1 to 2 feet thick (Merriam and Sorensen, 1982).
