Name Origin

The Scottville Limestone Member of the Modesto Formation (Payne, 1942, p. 4) is named for Scottville, Macoupin County.

Type Section

The type section consists of exposures along Apple Creek near the town (W 1/2 SW 16, 12N-9W) (Wanless, 1956, p. 11).


It is probably equivalent to part of the West Franklin Limestone of southeastern Illinois.

Extent and Thickness

The Scottville Limestone occurs in southwestern Illinois, where it is as much as 3 feet thick.


It is a light gray, fine-grained limestone.


The Scottville locally contains abundant Osagia, phylloid algae, and a diverse open-marine fauna.
