The Society Logo

 
The BCGS logo features the famous ‘Dudley Bug’ Calymene blumenbachii. This iconic trilobite is special to the Black Country, because it was historically collected from the local limestone mines and was present in Dudley’s former coat of arms.

Sir Roderick Impey Murchison published a comprehensive work on the Silurian Period in Great Britain and elsewhere in 1839. His book, The Silurian System described the geology and fossils from the Palaeozoic and provided excellent illustrations of the fauna, of which 65% of his evidence was from Dudley. The illustrations were carefully hand drawn by Murchison’s wife, Lady Charlotte Murchison.
