connorp Posted January 28, 2022 Share Posted January 28, 2022 I collected this specimen a while ago from the Liberty Formation (Upper Ordovician, Cincinnatian) of Indiana. Honestly, I have no idea what the heck it is. I posted this elsewhere and some thought it might be a strange echinoderm fragment, others thought it might not even be a fossil. Anyone seem anything similar before? Link to comment Share on other sites More sharing options...

Ludwigia Posted January 28, 2022 Share Posted January 28, 2022 I would agree that the outward appearance is quite echinodermian, but whatever it is in the end, it is strongly mineralized, which erases the sculptural traits and hinders a good id. 1 Greetings from the Lake of Constance.
