Crinoids or Sea Lilies (Crinoidea) are a group of invertebrate animals belonging to the main phylum Echinodermata (Echinodermata), which resemble plants in appearance. The species name comes from the Greek words "krinon" (lily) and "eidos" (form). The term "sea lilies" can refer to the entire class Crinoidea, but it can also mean only the stemmed members of the class, while the stemless ones are called hair stars (Comatulida). There are about 600 known living species of the class of sea lilies. Some of these live in the depths of the oceans (up to more than 9,000 meters deep) while others live in shallow (about 200 meters deep) coral reefs. More than 5,000 species have been identified from fossils. Sea lilies evolved as early as the Ordovician period about 485 million years ago, or possibly much earlier.

Note! Fossils are natural products that are millions of years old, so each one is unique. Therefore, colors, shapes and brightness may vary. The condition varies from fair to good and there are typical wear, fractures and small chips for fossils.
