The Pliocene history of northern and central Mississippi

The record of Pliocene time in northern and central Mississippi is generally assumed to be scant or lacking. The published geologic maps of this region show no Pliocene formations, and the only deposit in the region that has been assigned to the Pliocene is the un-mapped so-called Lafayette formation. This formation, however, in recent years has lost some of its good standing, for several students have become convinced that the material constitution the "Lafayette" in Mississippi has been altogether misinterpreted, most of it being simply more or less weathered material belonging to various underlying formations.

Geologic history indicated by the fossiliferous deposits of the Wilcox group (Eocene) at Meridian, Mississippi

The presence of erosion intervals at several horizons in the Eocene of the Gulf States has been pointed out in a recent paper, and the evidence of an erosion interval between the period of deposition of the sediments of the Wilcox group (lower Eocene) and that of the Claiborne group (middle Eocene) was reviewed in some detail in a general discussion of the extensive flora of the Wilcox group of that region.

The Catahoula sandstone

The name Catahoula was first used in 1905 by Veatch as a synonym for "typical Grand Gulf," but the description of the formation, which is here quoted, was not published until the following year.
