This listing features an authentic Crinoid Star Stem Fossil from the Lower Lias Formation of the Jurassic Period, discovered at Seatown, Dorset, UK — a location famous for yielding high-quality marine fossils from the early Jurassic seas

Crinoids are an ancient group of marine echinoderms, related to sea urchins and starfish. First appearing in the Middle Cambrian over 500 million years ago, crinoids were especially abundant during the Paleozoic and Mesozoic eras. This particular specimen dates to the Early Jurassic, approximately 200 million years ago.

Often referred to as "sea lilies", crinoids are named from the Greek words krinon (lily) and eidos (form), due to their flower-like appearance when alive. Unlike actual plants, crinoids were animals that lived anchored to the sea floor by a long stalk made up of star-shaped columnals — the feature visible in this fossil.

These columnals, or individual stem segments, are highly recognisable and make for unique and attractive fossil specimens. Crinoids were filter feeders, using feathery arms to catch plankton and other microscopic organisms from the water.
