9.8" Plate With Two Fossil Crinoids & Bryozoans - Missouri

 
 
This are two crinoids of the genus' Dizygocrinus and Hypselocrinus? that were collected from the Keokuk Formation of Randolph County, Missouri. The rock has been meticulously removed using air abrasives to reveal the beautiful structure of these crinoids. There are bryozoan fossils that have been partially exposed, scattered throughout the rock.

The genus of crinoid with the long stem is believed to be Hypselocrinus. This crinoid has multiple repaired cracks through the crown. There is a small additional crinoid that remains unidentified due to lack of detail. 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.
