Stratigraphic relationships
Extent and thickness
It is a thin limestone, rarely more than about 8 feet thick and commonly only 3 or 4 feet (fig. M-44). However, in extreme southern Illinois the limestone thickens rapidly to 30 feet (fig. M-1A). Until recently, the calcareous shale locally present above and below the limestone bed was assigned to the Vienna (Swann, 1963).
Lithology
The limestone is mainly dark brownish gray, but some is brown or dark gray. It is generally very fossiliferous, with crinoid fragments predominating. It contains dark chocolate-brown chert nodules in the outcrop, but chert is rare in subsurface. Locally some beds are sandy. In places thin beds and partings of shale are interbedded with the limestone.

Fossils
The fauna includes the bryozoan Prismopora serrulata, which is also abundant in the Glen Dean, and the pelecypod Sulcatopinna missouriensis, which is abundant in the Menard.
