Phanocrinus Crinoid From Alabama

This is a nicely preserved crown of a Mississipian aged crinoid (Platycrinites penicillus) from Alabama. It has been cleaned using air abrasives.

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.
