The physical conditions indicated by the flora of the Calvert formation
Edward Wilber Berry
1917, Professional Paper 98-F
The object of the present paper is to give a summary of the small flora preserved in the Miocene diatomaceous beds of the Calvert formation in the District of Columbia and Virginia, and more especially to discuss its bearing on the physical conditions of the Calvert epoch. Subsequent to the...

Geologic history indicated by the fossiliferous deposits of the Wilcox group (Eocene) at Meridian, Mississippi
Edward Wilber Berry
1917, Professional Paper 108-E
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...
Wasatch fossils in so-called Fort Union beds of the Powder River Basin, Wyoming, and their bearing on the stratigraphy of the region
Carroll H. Wegemann

In 1881 Eugene A. Smith announced the presence, underlying large areas in both western and peninsular Florida, of limestone which he correlated with the Vicksburg limestone of Mississippi and Alabama and designated by the term Vicksburg limestone. Among the localities he mentioned specifically are Marianna, in Jackson County, and Ocala,...
