Summary:

Hawxby Shale Member of Onaga Shale of Admire Group. Overlies Aspinwall Limestone Member of Onaga and underlies Falls City Limestone of Admire. Consists of fossiliferous shale and mudstone (paleosols); locally includes limestone lens at top. Contains bryozoans, crinoids, brachiopods, and ADETOGNATHUS conodonts. Interpreted to be nearshore marine deposits. Age is Late Pennsylvanian (late Gzhelian; STREPTOGNATHODUS BELLUS conodont zone), based on stratigraphic position.
Described from measured sections in Chautauqua, Greenwood, and Pottawatomie Counties, eastern Kansas, and Osage County, northern Oklahoma. (Locs. 1, 2, 3, A12, A15, A26.)
