minnbuckeye Posted July 11, 2019 Share Posted July 11, 2019 Chert Nodule???? Unfortunately not a fossil. These chert concretions are quite common in certain layers in SE Minnesota and NE Iowa where I hunt Link to comment Share on other sites More sharing options...

minnbuckeye Posted July 11, 2019 Share Posted July 11, 2019 I looked up Jasper County. It is likely Devonian, not Ordovician as is the rock in NE Iowa. With that said, I do hunt in a few quarries just east of you. There is a few layers with such structures in them too. I never paid too much attention to whether they were chert like. 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted July 11, 2019 Share Posted July 11, 2019 Concretion. Not fossil. Not bone. Just stone. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
minnbuckeye Posted July 11, 2019 Share Posted July 11, 2019 I just checked the quarry geology. Chalcedony nodules and chert are frequently found in certain formations (Wapsipinicon). 2 Link to comment Share on other sites More sharing options...

To me it looks more like grains than pores. Specimen looks geological to me. Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

ynot Posted July 12, 2019 Share Posted July 12, 2019 I agree with a silicate concretion/nodule. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Plowboy1270 Posted July 12, 2019 Author Share Posted July 12, 2019 Thanks for everyone’s input. It just seemed out of the norm so I had to ask. Link to comment Share on other sites More sharing options...

If you would like to join the club and attend, let me know and I will let Marv know and count you in. There is limited spots. (3) Sunday, July 28, CVRMS field trip to Klein Quarry.
