Geological Guide to Daddy Hole
Daddyhole Limestone
At Daddy Hole, the rocks are Middle Devonian of the Eifelian Stage. Approximately 380 to 391 million years ago. Indications suggest that at Daddy Hole, the marine life lived and died in shallow. quiet water. The Thinly bedded limestone's vary from calcareous mud's to fragmental limestone's. Fossils can be found both in the limestone's and the calcareous mud within sandy deposits and were abundant in colonies which is why groups of fossils can be found together.
