Tiesta posted a topic in MinnesotaHopefully this picture works. I found this one a few weeks ago in lilydale - seem to be soft Decorah limestone. For a bit while I thought it was a unusual feeding tracks type but the patterns seem to be too regular - I can't see any exoskeletions on this one that would be typical of crinoids but my research hadn't come up with anything else for it. Nothing in books and internet about echinodermata that looks like this one. The only way to describe it is all the branches come from the central stem section and that it once had some kind of organic skeleton that held together long enough for fine sediments to get in before rotted away completely leaving behind a mold.
