Hello, I know the photo is lacking. Going to look for a camera tonight. Nonetheless, here is a fossil from the Dundee of Ohio. Wondering if anyone has any thoughts on this being a Cyclocystoid, and if you have found similar in the Dundee anywhere. Thanks (And if so, what was your identification)

Last November, my wife and I went collecting in northern Kentucky. We had visted a Richmondian site and were on our way back, when we happened to see a random road cut and decided to pull over and have a look. It was composed of blocky limestone rich with Vinlandostrophia ponderosa, and turned out to be part of the Bellvue Mbr. of the Grant Lake Fm. Within about 10-15 minutes, my wife found her first cyclocystoid, and I found my first edrioasteroid. As far as rarity, I'd say she definitely outdid me! These fossils got our hopes up for more, but the rest of the day plus a second trip with friends failed to find any additional echinoderms. My wife's cyclocystoid measures about 12 mm in diameter. We don't know the species yet, but we are planning to meet with a paleontologist in Cincinnati soon to ID it. My edrioasteroid is Isorophus cincinnatiensis, measures about 17 mm in diameter, and is upside down and partially broken. Jack Kallmeyer of the Dry Dredgers suggested it was likely attached to a clam during life, which then dissolved away after burial, leaving the underside exposed.
