Bev Posted October 19, 2013 Share Posted October 19, 2013 Ordovician. Probably Galena Formation. SE MN. Sorta kinda reminds me of chert. Then there is that thing on top in the first pic. Also reminds me of bone - very smooth. Or it could just be a rock... :-D Thanks for looking! The more I learn, I realize the less I know.

PennyT. Posted October 29, 2013 Share Posted October 29, 2013 Bev, lots of chert around my part of the planet. It can be such cool shapes and colors. Link to comment Share on other sites More sharing options...
Joe D. Posted October 29, 2013 Share Posted October 29, 2013 The second picture looks like "dogtooth Quartz". There is a tiny formation of Quartz crystals running along the lower middle. It is too "crystaline" to be Chert, but then its all in the family. It's definitely not bone. Joe D. Link to comment Share on other sites More sharing options...
