Archie Posted January 18, 2020 Share Posted January 18, 2020 2A looks like it could be a coiled cephalopod or possibly a gastropod. 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted January 18, 2020 Share Posted January 18, 2020 I agree with Archie. It's hard to tell with the others since the camera keeps moving around. Photos would be better for my old eyes. Stratigraphy? Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Darrell Barnes Posted January 19, 2020 Author Share Posted January 19, 2020 https://www.uky.edu/KGS/geoky/quaternary.htm Ordovician, Mississippian or Pennsylvanian Berea is south of Lexington, KY The nodules were found roadside in strata in a part of Kentucky called the "knobs." https://www.uky.edu/KGS/geoky/fieldtrip/fort_payne/stratigraphy/stratigraphy_relationships.htm I am not a geologist.....Coffee formation sounds familiar.

Wrangellian Posted January 28, 2020 Share Posted January 28, 2020 I see septa in those sliced pieces, which would indicate nautiloid. Interesting... I wonder how they would look prepped (airscribed) from the outside. Link to comment Share on other sites More sharing options...
minnbuckeye Posted January 28, 2020 Share Posted January 28, 2020 On 1/18/2020 at 6:10 PM, Darrell Barnes said: part of Kentucky called the "knobs." Does this refer to "the mounds" depicted on your reference map? Does anyone know what caused the "mounds" in the Fort Payne? Mike Link to comment Share on other sites More sharing options...
Darrell Barnes Posted January 31, 2020 Author Share Posted January 31, 2020 I think the "knobs" are Appalachian geographic features in Kentucky. They are small mountains and I would not call them mounds. With this said, I am not a geologist. Link to comment Share on other sites More sharing options...
