Sellers Limestone Member
M. E. Hopkins and J. A. Simon
The Sellers Limestone Member of the Caseyville Formation (Wanless, 1939, p. 36, 101) is named for Sellers Landing, Hardin County.
The type section is on the west bank of the Ohio River, at Sellers Landing (21, 11S-10E) (Wanless, 1956, p. 9).
It is equivalent to part of the Drury Shale, but no limestone correlatives are known.
Extent and Thickness
The Sellers Limestone is known only at the type locality, where about 10 feet is exposed.
Part of the limestone is sandy and coarse grained and contains a varied marine fauna, but most of the Sellers is composed of beds of very fine-grained, argillaceous limestone interbedded with gray shale.
No fusulinids, ostracodes, or conodonts have been found in the Sellers.
It is a major marine deposit in a complex fluvial-deltaic sequence.
