Precambrian Nomenclature in Kansas, Robert S. Sawin, Evan K. Franseen, Greg A. Ludvigson, W. Lynn Watney, and Ronald R. West

Abstract

The informal stratigraphic term "Precambrian" is replaced by formal nomenclature--Proterozoic and Archean Eonothems/Eons--and the informal term Hadean. The Phanerozoic Eonothem/Eon, representing all rocks younger than the Proterozoic, is added. The Proterozoic is further divided into Paleoproterozoic, Mesoproterozoic, and Neoproterozoic Erathems/Eras. The name Rice Formation (Scott, 1966) is abandoned, and the use of the informal term "Rice unit" is recommended. The proposed name Rice Series (Berendsen, 1994) is not accepted. These changes are adopted by the Kansas Geological Survey (KGS) and the stratigraphic nomenclature of Zeller (1968) has been revised accordingly.

Fusulinids from the Howe Limestone Member (Red Eagle Limestone, Council Grove Group) in Northeastern Kansas and their Significance to the North American Carboniferous (Pennsylvanian)-Permian Boundary, Gregory P. Wahlman and Ronald R. West

Abstract

Fusulinids from the Howe Limestone Member (upper part of the Red Eagle Limestone, lower part of the Council Grove Group) are described here for the first time. The fauna is particularly significant because it represents the first fusulinids known above the new conodont-based midcontinent Carboniferous (Pennsylvanian)-Permian boundary at the Glenrock Limestone Member-Bennett Shale Member contact in the lower part of the Red Eagle Limestone.
