TqB Posted August 8, 2022 Share Posted August 8, 2022 Nautiloid siphuncle I think. You can see traces of the enclosing chambers at the top end. 2 Tarquin Link to comment Share on other sites More sharing options...
BobWill Posted August 8, 2022 Share Posted August 8, 2022 Is that a piece of wire on the bottom right? It makes me wonder if you have the impression of a piece of rebar in concrete. Link to comment Share on other sites More sharing options...

No, it looks like a stick/branch of some sort when you zoom in on it. 1 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

rocket Posted August 8, 2022 Share Posted August 8, 2022 (edited) Interesting one, do you have a pic of the cross-section? Reminds me to a orthocone cephalopode, something like Gorbyoceras / Striatocyloceras but, when I see your tags seems to come from wisconsin perhaps Spyroceras, when I compare plate 6, fig a in Common Paleozoic fossils of Wisconsin Edited August 8, 2022 by rocket 1 Link to comment Share on other sites More sharing options...
