Name Origin

The Shetlerville Limestone Member of the Renault Formation (S. Weller, in S. Weller et al., 1920, p. 123; Swann, 1963, p. 82) is named for Shetlerville, Hardin County.

Type Section

Weller designated the Shetlerville Member a formation, citing exposures of about 30 feet of limestone just east of Shetlerville as the type section. Swann (1963) put the upper shaly part in the Yankeetown, restricted the Shetlerville to 15 feet of limestone exposed in a quarry one-fourth of a mile south of Shetlerville (SE NE SW 35, 12S-7E), and classified it as a member of the Renault.


Most of the limestone is dark greenish or brownish gray, sandy, and oolitic. The basal portion grades to sandstone and is named the Popcorn Sandstone Bed. Some beds are light colored and resemble the underlying Levias Member. The basal contact is sharp and may be unconformable.


The Shetlerville contains the crinoid Talarocrinus (fig. M-4) and is the basal part of the Chesterian Series.
