The riverbed at Rock Glen Conservation Area is famous for its Devonian-era fossils, dating back more than 350 million years, long before dinosaurs existed. At that time, this region was covered by a shallow tropical sea. As Rock Glen Falls and the Ausable River erode the surrounding rock layers, fossils are continually exposed along the creek bed. Visitors often spot remains of ancient marine life such as brachiopods, horn corals, and crinoid stems embedded in the limestone. Fossil collecting is allowed here, but only one fossil per person may be taken and digging or tools are not permitted.
