Abstract
"The type locality of the Archusa marl member of the Wautubbee formation is situated south of Quitman, Clarke County, Mississippi. Stratigraphically, the unit falls within the middle Eocene Claiborne group, being roughly equivalent to the upper part of the Lisbon formation of Alabama and the lower part of the Cook Mountain. The marl falls within the Ostrea sellaefonnis zone and the zone of "Ceratobulimina eximia.” The type section consists of 48 feet of sandy marls, with a thin oyster bed near the middle.
The Archusa foraminifera fauna consists of 87 species and varieties, belonging to 49 genera and 18 families. These, together with the associated fauna and lithic constitution of the marl, indicate deposition in a partly enclosed marine embayment of moderate depth (40-60 fathoms). A previously unrecognized depositional sub-cycle, within the Archusa marl member, involved shallowing and deepening of the embayment, the oyster bed representing the period of shallowest water"--Introduction, page 1.
