Abstract

Goniatites are rare in the Devonian strata of Iowa, but a few have been found in the Independence, the Cedar Valley, and the Lime Creek formations. In view of the superiority of ammonoids for purposes of detailed correlation, and because of the uncertainty that exists in regard to the exact age of some of the Devonian beds of Iowa, it seemed to me that a summary of our present knowledge of Iowa Devonian ammonoids should be compiled and made readily available. It is hoped that this summary will help, either directly or indirectly, with some of the stratigraphic problems that are now pending, and that, in addition, it will stimulate Iowa geologists to look for more and better preserved goniatites in our Devonian rocks.
