The Reelsville Limestone Member of the Ridenhower Formation (Malott, 1919, p. 10-11).

The Reelsville Limestone Member is the uppermost member of the Ridenhower Formation.
Extent and thickness
The Reelsville is classified as a formation in Indiana. It is dominantly limestone but contains beds of shale. It is not differentiated in the type section of the Ridenhower Formation, and it has limited distribution in southeastern Illinois, mostly in subsurface. The Agassizocrinus cf. leavis Peak Zone is equivalent to the Reelsville Member.
