Echinodermata

Echinoderms include well-known sea animals like the starfish (Asteroidea), brittle stars (Ophiuroidea), sea urchins and sand dollars (Echinoidea), sea cucumbers (Holothuroidea), and sea lilies (Crinoidea). Fossils of all these classes of echinoderms plus the extinct classes Blastoidea and Edrioasteroidea have been found in Kentucky. By far the most abundant are the crinoid and blastoid fossils; fossils from the other classes are fairly rare.
