Overview

Excerpt from Stratigraphy and Correlation of the Devonian of Western Tennessee The Devonian strata exposed along the Western Valley of the Tennessee River have for more than half a century offered one of the most inviting fields to the stratigrapher and paleontologist. Not only are they replete with finely preserved fossils, but the long sequence - especially the presence of the typical upper Oriskany - will make it the standard section for the Lower Devonian of the entire Mississippi basin. Nevertheless, in spite of their significance, these strata have received only the scantiest attention and they have remained the last important area of Lower Devonian rocks in America to be adequately described. The present study of these strata was begun in the summer of 1916, when the writer spent two months in the field, making a large collection of fossils and gathering data which formed the basis for a dissertation presented in 1917 in partial fulfillment of the require ments for the degree of doctor of philosophy at Yale University. The problem proved so fruitful of interesting results that through the interest of the late Doctor A. H. Purdue, the Tennessee State Geological Survey enabled the writer to spend five additional weeks in the field during the summer of 1917, and to prepare the present monograph.
