Overview

Excerpt from Pottsville Fauna of Ohio The collections were made chiefly during the summers of 1918 and 1919, and the manuscript was prepared for the most part during the summer of 1920 and the following university year. In most instances large quantities of fossiliferous rock were collected, from which the fossils were later obtained and prepared for study in the laboratory. The fossils used in this investigation are the property of the Geological Survey of Ohio, and all types, figured specimens, and forms of unusual interest have been placed in the Geological Museum of The Ohio State University. The portion of this bulletin which deals with the strati graphy and fauna of the Pottsville formation below the Lower Mercer limestone was submitted in June, 1921, to the faculty of Bryn Mawr College in partial fulfillment of the requirements for the degree of Doctor of Philosophy.
