Crinoids, commonly known as sea lilies, are ocean dwelling creatures that lived attached to the sea floor. They consist of three main body parts: the arms that filter food particles out of the water, the head (or calyx) that houses the internal organs and mouth parts, and the stem that attaches the crinoid to the sea floor. In spite of their plant-like appearance, crinoids are animals. They belong to a phylum of sea creatures known as Echinodermata, meaning "spiny skin." Examples of other non-extinct echinoderms include sea urchins, sand dollars, sea cucumbers, and starfish.

The original fossils represented here (have not been identified) were found in Montgomery County, Indiana, in the marine deposits of the Edwardsville Formation. These sediments date back approximately 345 million years to the Mississippian Age when crinoids reached their peak, carpeting the floors of shallow seas. The Mississippian Age has been dubbed "The Age of Crinoids." From the fossil record about 2,100 crinoid species are known and 800 species survive today. Modern day crinoids live at great depths in the ocean. Since echinoderms disarticulate easily when they die, pieces of fossilized crinoid stems are commonly found but complete crinoids are a rare and treasured find.
