1.8" Unidentified Fossil Crinoid - Alabama

This is a 1.8", unidentified fossil crinoid from the Bangor Limestone, Franklin County, Alabama. It shows the segments that make up the skeletal shell of the crinoid. Washer shaped sections are from the stem, octagonal or other quadrilateral shapes are the calyx and round flat plates made up the feeding arms of the animal. It is too disarticulated to make any accurate determination as to genus or species.

Crinoids, sometimes commonly referred to as sea lilies, are animals, not plants. They are echinoderms related to starfish, sea urchins, and brittle stars. Many crinoid traits are like other members of their phylum; such traits include tube feet, radial symmetry, a water vascular system, and appendages in multiples of five (pentameral). They first appeared in the Ordovician (488 million years ago) and some species are still alive today.
