It was discovered in the Salthill Quarry, Clitheroe, Lancashire, UK, a site known for its rich deposits of early Carboniferous marine fossils. Crinoids, also known as “Sea Lilies,” are marine echinoderms related to modern sea stars and sea urchins.

This well-preserved calyx (cup) showcases intricate features of its ancient feeding structure. This fossil originates from the Alice Purnell Collection, one of the largest and most renowned fossil collections in the world.
