Natural Devonian prehistoric Jurassic biota crinoids Fossils For Sale

lilies are echinoderms that first appeared in the Early Cambrian, living in the sea with multiple arms and feet, a flower-shaped body, and a calcareous shell on the surface. Because they look like plants, people named them Sea lilies.\".The body of sea lilies has a handle like a plant stem, and the feathery things on the top of the handle are their tentacles, also known as wrists. These tentacles, like the leaves of ferns, confuse people with the idea that they are plants. Sea lilies are an ancient invertebrate. Hundreds of millions of years ago, they were everywhere in the ocean.
