Uncover a rare and iconic piece of Britain’s paleontological history with this Calymene blumenbachi trilobite fossil tail, commonly known as the “Dudley Bug”, from the Much Wenlock Limestone Formation of the Silurian Period, found at the famous Wren’s Nest in Dudley, West Midlands, UK. Known for its detailed segmentation and ability to enroll for protection, this trilobite has become a symbol of Dudley’s rich geological heritage.
