Bev Posted September 23, 2013 Share Posted September 23, 2013 Ordovician. Probably Galena Formation. SE MN. I'm thinking that this is the gastropod Ceratopea sp. I have the 10th printing of The Index Fossils of N.A., plate 181 on page 447, reference to Ulrich 1911. I also did a Google advanced image search which seemed to back this up. My two concerns are: 1. It doesn't have the typical point. 2. The hollow on top appears to be filled in or has the fossilized "foot". But, these could be due to the fossilization process. OR, it could just be a rock and I have quite the imagination! LOL :-D Thoughts? Speculation? Thanks for looking! Bev The more I learn, I realize the less I know.

Indy Posted September 23, 2013 Share Posted September 23, 2013 OR, it could just be a rock and I have quite the imagination! LOL :-D I'll agree you do have a wonderful imagination. Seriously, I don't see anything which would bring gastropod to mind. Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
Caleb Posted September 23, 2013 Share Posted September 23, 2013 Ceratopea is a Lower Ordovician gastropod and the Galena Formation is Upper/Late Ordovician in age. In Minnesota Ceratopea is listed as being from the Shokopee Dolomite of the Prarie Du Chien Group which is exposed on top of the bluffs along the Root River, so it may be possible to find them. However, I believe that this specimen you posted may very well be just a rock. 1 Caleb Midwestpaleo.com Link to comment Share on other sites More sharing options...

RichW9090 Posted September 23, 2013 Share Posted September 23, 2013 Bev, do you have a Golden Retriever? The plural of "anecdote" is not "evidence". Link to comment Share on other sites More sharing options...
Indy Posted September 23, 2013 Share Posted September 23, 2013 Bev, do you have a Golden Retriever? Very funny !! I had a Golden Retriever once ... brought me anything he could hold in his mouth or drag.

Bev Posted September 23, 2013 Author Share Posted September 23, 2013 I have Collie's and they don't even fetch! I found this rock on a beach in the Root River. Actually, I was telling Indy that I was just up to the North Shore of Lake Superior (stunningly gorgeous by the way) and have come back with a whole new appreciation of rocks and minerals! Besides, I am like a kid in a new sandbox! And hey, it doesn't hurt to ask questions! You guys can always ignore me! One of the centerpieces of my collection is a big agatized rock I picked up on the beach this summer that turned out to be the internal mold of a brach! I thought it was just an odd rock and threw it on a discard pile, then came back to it, took pictures and asked... Now it is front and center in my collection! Bev :-D The more I learn, I realize the less I know.

BobWill Posted September 23, 2013 Share Posted September 23, 2013 I could be wrong (again) but I think Rich was suggesting your rock looks like something a Golden Retriever might leave behind Link to comment Share on other sites More sharing options...
Bev Posted September 23, 2013 Author Share Posted September 23, 2013 Well, see there... And Indy did mention coprolite, or however you spell it - dino dung!

Indy Posted September 23, 2013 Share Posted September 23, 2013 Well, see there... And Indy did mention coprolite, or however you spell it - dino dung! Don't start any rumours ... I only said it might bring coprolite to mind but followed up by saying it isn't coprolite.
