Abstract
The bioherms present in the Silurian of eastern Iowa are confined to the Niagaran Series and are largely restricted to the Gower Dolo mite. Those described here are solely Goweran. Four of the bioherms were chosen for detailed study from the hundreds present, as being typical of the Iowa structure and individually offering exposures of elements which no single bioherm displayed. Typically, they are oval mounds of undisclosed heights some exceeding 180 feet. They range from a few tens of feet to at least a quarter mile in diameter.
