matgerke Posted January 10, 2021 Share Posted January 10, 2021 Found this ammonite or gastropod this afternoon between Capon Bridge and Wardensville. The formation is supposed to be Oriskany Sandstone, but it looked like siltstone not sandstone. Is this an ammonite or a gastropod? It seems too big to be a gastropod to me, but wanted to check, as I've never found an ammonite in the area before. Thanks! Matt Link to comment Share on other sites More sharing options...

BobWill Posted January 11, 2021 Share Posted January 11, 2021 No ammonites in the Devonian. If it's an ammonoid it would be a goniatite but it could also be a nautiloid and I should add that gastropods can get much larger than that so size is not a reason to exclude the possibility. It's not a formation or even a period I an familiar with but without more ornamentation showing you may need a fauna list for the area to help Id by elimination.

ScottBlooded Posted January 11, 2021 Share Posted January 11, 2021 I have found a lot of these out in this area, I asked on here about what exactly they were and got mixed answers. Was the material shale like? Pretty sharp? Because from that photo it looks more like the needmore formation, but I could be wrong. That’s the formation I’ve found them in at least. 2 Link to comment Share on other sites More sharing options...
matgerke Posted January 11, 2021 Author Share Posted January 11, 2021 Yes, I think it may be needmore formation -- hard to say. It's definitely shale and not sandstone. Link to comment Share on other sites More sharing options...
Ludwigia Posted January 11, 2021 Share Posted January 11, 2021 I'm still open for the possibility that it's a gastropod, but it's really hard to decide based just on this one photo. Any way you can prep the fossil out of the matrix for a better analysis? Greetings from the Lake of Constance.
