Pg. 42, 52, 53. Coal Creek limestone bed of Topeka limestone member of Shawnee formation. The upper unit of Topeka limestone was named Union limestone by Condra and Bengston in 1915 (Nebraska Acad. Sci. Pubs., v. 9, no. 2). That name being preoccuppied the division is here named Coal Creek limestone, from exposures on Coal Creek, north of Union, [Cass County], southeastern Nebraska. The limestone is dark blue, dense, brittle, and quite fossiliferous. At Places it is split into 2 or 3 beds. Thickness 5+ feet in southeastern Nebraska and northwestern Missouri, 4+ feet in southwestern Iowa, and 3+ feet northeastern Kansas. Overlies Holt shale. Age is Late Pennsylvanian (Missouri age). Report includes cross sections, measured sections, geologic maps, stratigraphic tables.

Pg. 126 (fig. 22), 164-165. Coal Creek limestone member of Topeka formation; overlies Holt shale member; underlies Severy shale of Wabaunsee group. This classification agreed upon by State Geological Surveys of Iowa, Kansas, Missouri, Nebraska, and Oklahoma, May 1947. In Kansas, consists of light-bluish-gray limestone and nodular shale or dark-blue massive limestone which weathers light bluish gray or brown. Thickness 2 to 5 feet. Not positively identified south of Kansas River. Age is Late Pennsylvanian (Virgilian).

(Paleozoic Era; Pennsylvanian System by J.M Jewett, H.G. O'Connor, and D.E. Zeller, p. 38.) Coal Creek Limestone Member of Topeka Limestone of Shawnee Group. Recognized in northeastern Kansas, but it is only locally identified in southeastern Kansas. Consists of light bluish-gray limestone and nodular shale or dark-blue, more massive limestone that weathers light bluish-gray or brown. Fusulinids are abundant, and at many places numerous other well-preserved invertebrate fossils are found. Thickness from 2 to 8.5 feet. Occurs above Holt Shale Member of Topeka Limestone and below Severy Shale of Sacfox subgroup [informal] of Wabaunsee Group. Age is Late Pennsylvanian (Virgilian).
["Subgroup" not recognized as a formal stratigraphic rank term (CSN, 1933; ACSN, 1961, 1970; NACSN, 1983, 2005, 2021). Considered informal and should not be capitalized.]
