Silurian crinoid fossil (Periechocrinus)

This is a limestone slab with beautifully preserved crinoid fossils (*Periechocrinus costatus*; BU2470, BIRUG 4899) on display in the Evolution of Life gallery of the Lapworth Museum of Geology. The crinoids come from the 428 million-year-old Much Wenlock Limestone Formation of Dudley, West Midlands, UK. In the Silurian the West Midlands was covered by warm shallow tropical seas, and a diverse ecosystem lived on and around coral and sponge reefs on the sea floor.
