“Foerstediscus splendens” is an extinct echinoderm (a member of the group including sea stars, sea urchins, and sea lilies) known as an edrioasteroid (seated star) that lived during the Ordovician. Fossils of “Foerstediscus” have been found at Mississippi National River and Recreation Area, Minnesota.

Have you ever been fossil hunting? If you are interested in collecting fossils, you should plan an adventure to the Fossil and Prairie Park Preserve in Rockford, Iowa. It gives you a chance to find your own fossils.

Did you know that Iowa is only one of a handful of state’s that doesn’t have a state fossil? There is currently a proposal for the Crinoid to become Iowa’s State Fossil. Crinoids are a class of animals called echinoderms that first appears on the earth about 500 million years ago. They have two form, sea lilies (stalked form attached to the sea floor) and feather stars (free-living.) Learn more about the Crinoid at the Cedar Valley Rocks and Mineral Society website.
