Description

Excerpt from The Physical Conditions Indicated by the Flora of the Calvert Formation The object of the present paper is to give a summary of the small flora preserved in the Miocene diatomaceous beds of the Calvert for mation in the District of Columbia and Virginia, and more especially to discuss its bearing on the physical conditions of the Calvert epoch. Sub sequent to the middle Eocene the next abun dant marine fauna preserved along the middle Atlantic coast is that of the Calvert formation of the Chesapeake group. Although Miocene faunas so low in the stratigraphic column are known south of Virginia only in the vicinity of Porters Landing, Savannah River, Ga., closely related but younger Miocene faunas extend southward at least as far as Florida, where the containing formation rests unconformably on beds in which occur the warmer - water faunas of the Apalachicola group.
