CRINOID FOSSILS FOR SALE
Crinoids, sometimes commonly referred to as sea lilies are animals not plants. They are echinoderms related to starfish, sea urchins and brittle stars. Crinoids are marine filter feeders that have a collection of branching arms on top of a stem. While most spend their lives fixed to the bottom but some are free swimming or capable of crawling. With skeletons made of calcium carbonate they make great, detailed fossils.
