Kurvinosaurus Posted May 21 Share Posted May 21 Hello! I’ve been doing some fossil and rock hunting on a Lake Michigan beach in Wisconsin, and I was just wondering if this could be a crinoid fossil? There’s chain coral in the rock on both sides. I tried sanding a little around what I think is the crinoid, but I didn’t uncover anything else. Thank you for any help!

DPS Ammonite Posted May 21 Share Posted May 21 (edited) Yes a chain coral: Hallysites. See similar Lake Michigan fossil from fossillady.com website: https://fossillady.com/tag/halysite-coral-facts/ Edited May 21 by DPS Ammonite My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere. Link to comment Share on other sites More sharing options...
connorp Posted May 21 Share Posted May 21 The other thing is probably a coral or bryozoan, but I can't make out much detail to tell which. Not a crinoid though. 1 Link to comment Share on other sites More sharing options...
