The purpose of this paper is to describe the Dundee limestone in southeastern Michigan so that sections in other parts of the state may be compared, both as to stratigraphy and as to fauna, with that of the type area. The name, Dundee, is generally used to designate all limestone beds occupying a stratigraphic position between the Detroit River group, composed largely of dolomites, and the overlying shales and limestones, assigned to the Traverse group. As these limestones are not of the same age in different parts of the state, the writer has made a careful study of the strata and the fauna of the type area. It is hoped that this information will help others in their work on the succession and the correlation of this formation.
For aid in this investigation the author is greatly indebted to Professor G. M. Ehlers, of . . .
