The trilobite fossil Calymene blumenbachii is so common in the local rocks that it was adopted as the symbol of the limestone mining industry and appeared in the centre of the town's coat of arms. It is more widely known by its nickname the 'Dudley Locust' or 'Dudley Bug'.
Sir Roderick Murchison visited Dudley in 1839 and 1849 to address members of the British Association inside Dark Cavern - by gaslight. An estimated 15,000 people attended each event, with Murchison being acclaimed 'King of Siluria' at Wren's Nest.
These remarkable events have since become part of both local and scientific 'lore'.
The Black Country Museum is a museum of buildings which celebrates the industrial past of the region. Built on the site of 18th century collieries and at the entrance to the underground canal system, it utilises some of the original industrial features including 18th century mine shafts and the mid 19th century giant draw kilns and accompanying canal basins and canal.
Dudley Borough maintains a definitive collection of fossils from Wren's Nest and Castle Hill. This collection was established following the publication of 'The Silurian System' and boasts specimens figured by Murchison.
