Stratigraphic relationships

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.




Well log characteristics


No fusulinids, ostracodes, or conodonts have been found in the Sellers.

Age and correlation

It is equivalent to part of the Drury Shale, but no limestone correlatives are known.

Environments of deposition

It is a major marine deposit in a complex fluvial-deltaic sequence.
