minnbuckeye Posted October 8, 2018 Author Share Posted October 8, 2018 @Bullsnake, I really thought you nailed the ID. but as I went to label this as a likely possibility, I noticed it was a stereo isomer of it, it swirls in the opposite direction. Back to the drawing board. Report post Posted 23 hours ago @minnbuckeye Can you tell if it is conical? I found this in 'Index Fossils of North America'. It is widespread in the Ordovician/Silurian and known in the Mississippi valley. Eotomaria spp. The one circled is Eotomaria supracingulata. I hope this helps, or at least is a lead. 1 Link to comment Share on other sites More sharing options...

I know that the genus Cyrtolites is found in my area (Upper Ordovician), and apparently it's also been found in the Upper Ordovician of Kentucky... lots of them in KY. 1 "Absence of evidence is not evidence of absence"_ Carl Sagen No trees were killed in this posting......however, many innocent electrons were diverted from where they originally intended to go.
