Crinoids or sea lilies belong to a group of animals,the Echinoderms,which also include starfish and sea urchins. Contrary to their appearance and their popular name "sea lilies",crinoids are animals and not plants. Crinoids have lived in shallow seas since very ancient geologic times and they still exist today. They have a long,thin stem attached to the seafloor,topped with a flower-shaped body that bears feathery petals. The limestone on which these fossil remains stand out comes from Carboniferous deposits near Crawfordsville,Indiana in the USA | |
