Four Ordovician Crinoids - Bobcaygeon Formation - Ontario

 
 
This is a lovely crinoid association from the Bobcaygeon Formation in Ontario, Canada, with four individual specimens present representing two different species. All are preserved 3D and have been prepared with air abrasives. This is a natural association and none of the specimens are composites.

Comes with an acrylic display stand.

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.
