Abstract

The coals of the Des Moines Series of Iowa contain an abundance of unassigned plant microfossils and in this report a few of the more diagnostic new types are described. At the present time little can be stated concerning the vertical distribution of these microfossils but preliminary work has shown that some are definitely restricted to certain strata and should become useful horizon markers as more information is accumulated. In 1940, Wilson and Coe described eleven new species of unassigned plant microfossils from the Des Moines Series of Iowa. Several of these have since been transferred to other genera by Schopf, Wilson, and Bentall (1944). The specimens that constitute the types of species described here are in the collection of the senior author. The authors wish to express their appreciation to Dr. Theodor Just, University of Notre Dame, for checking the construction of the new specific names used in this paper.
