Mortimer Forest, near Ludlow, preserves an internationally important record of Silurian seas in wooded quarries, stream banks and trackside cuttings. Brachiopods, corals, trilobites and graptolites accompany changes from limestone to mudstone and siltstone. The numbered geological trail, measured research sections and older informal collecting circuit are distinct routes, with access and sampling conditions to check before visiting.
