Crinoid fossils. Rock containing crinoid (or sea lily) fossils. These are Scyphocrinus elegans crinoids from the Silurian/Devonian period (about 440-360 million years ago). Crinoids are marine echinoderms that appear as early as the Ordovician period (500 million years ago). These crinoids have stalks by which they would attach themselves to the seabed, capturing food with feathery arms that formed a cup (seen at lower right and upper centre). Thousands of extinct crinoid species have been foundPenelope Jordan
