This is an impressive, museum quality slab of large Cactocrinus crinoids from the Gilmore City Formation in Iowa. There are over a dozen crowns with stems present on the solid 30 x 19" slab of limestone. It has been painstakingly prepared with air abrasives to reveal all of the details of these marvelous, 300 million year old echinoderms.

It comes with a display stand or we can add a backing and wall mounting hardware for an extra fee.

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.
