Crinoid fossil. Rock containing a crinoid, or sea lily, fossil. This is a Scyphocrinus elegans crinoid from the Silurian/Devonian epoch (440 to 360 million years ago). Crinoids are marine echinoderms that have been in existence for 500 million years. Thousands of extinct crinoid species have been found as fossils, but only a few hundred species still exist today. They attach themselves to the sea floor with their stem and use their feathery arms to filter food from the water. This fossil was found in Morocco.
