.7" Fossil Crinoid (Phanocrinus) in Rock - Alabama
This is a detailed Mississipian aged crinoid crown (Phanocrinus bellulus) from the Bangor Limestone in Alabama. This crinoid is partially exposed from the limestone rock it was found in.
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.
