odinsride Posted February 7, 2016 Share Posted February 7, 2016 I'm not a fossil hunter and don't know much about them but I found this today while panning for gold in SW Ohio. Was hoping someone could tell me what it is. Thanks! http://imgur.com/a/GsvEo Link to comment Share on other sites More sharing options...

BobWill Posted February 8, 2016 Share Posted February 8, 2016 Welcome to the forum. Those nautiloids were related to the present-day nautilus which grows in a coil like a snail instead of straight like yours. The partitions separated air chambers that filled in with minerals as it fossilized. The body chamber was much larger and, as usual, is missing. There are some remains of the siphuncle in the center. It was a tube that could drain water out of the chambers and replace it with air to adjust buoyancy and orientation for swimming like the swim bladder in a fish.
