It preserves fossils dating back to the Middle Devonian.

Description

The Dundee Limestone is named after Dundee, the area where the original outcrops were found . It is, as the name states, made up of limestones, though the makeup of the limestone change throughout the strata. These are able to be divided into two units. The upper strata of Dundee are made up of medium to course grain limestone and is where most fossils from the limestone are present. The lower strata are made up of sandy dolomite along with limestone and nodular chert.{{Cite journal |last=Smith |first=David A. |date=1972 |title=High-Calcium Limestone Facies of the Devonian Dundee Limestone, Northwest Ohio |journal=Report of Investigations |volume=86}}{{Cite journal |last=Janssens |first=A. |date=1970 |title=Middle Devonian Formations in the Subsurface of Northwestern Ohio |journal=Report of Investigations |volume=78}}

The limestone represents the Dundee Sea, a shallow sea named after the limestone. There is only a small amount of macrofossils known from the lower Dundee which contrasts the nearby Delaware Limestone. This lack of macrofossils can potentially be attributed to highly saline periods of time. As time went on, there is evidence that a lagoon or another near-shore environment formed, allowing for an influx of fauna.
