Abstract

"One of the most serious difficulties confronting anyone working on stratigraphic problems in the Ozark area is the lack of detailed faunal lists of the various formations. A great deal of general work has been done, but very few detailed faunal studies have ever been published, and correlation of the Missouri section with sections in adjoining states is often difficult. In a recent paper, Dake has discussed the origin and correlation of the St. Peter sandstone. In this study he found considerable difficulty in correlating the various formations above the St. Peter, and at his suggestion, the present study was undertaken in the hope that additional data regarding the fauna and correlation of these forms would be obtained. The area studied is located in the western part of St. Louis County ... The writing of this report was divided as follows: The Introduction was written by the senior author. The junior author has written the description of the sections, has identified the collections and compiled the faunal lists. The identification of the fossils was done under the supervision of the senior author, and he assumes all responsibility for the correctness of these identifications. The junior author is also to be credited with the drafting of the various columnar sections. The sections dealing with correlation and conclusions are the work of both authors" – Introduction, pages 1-3.
