.9" Mississippian Fossil Crinoid (Actinocrinites) Calyx - Iowa

This is a crinoid (Actinocrinites multiradiatus) fossil collected from the Mississippian-aged Burlington Formation in Burlington, Iowa. It has been exposed from the matrix 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.
