Darbi Posted June 15, 2020 Share Posted June 15, 2020 I'm guessing it's an iron concretion and not a fossil, but I would like to make sure. I have never seen anything like this shaped like a spikeball or flower, except in crystals. Fossil or not, I took it home because it's so interesting! Dakota formation and early Cenomainian. This formation are known for fossilized plants, leaf imprints, and petrified woods. Top view: Bottom view: Link to comment Share on other sites More sharing options...
grandpa Posted June 15, 2020 Share Posted June 15, 2020 I believe this is limonite after marcasite. Beautiful specimen. Hang on to it. 8 Link to comment Share on other sites More sharing options...

Mark Kmiecik Posted June 19, 2020 Share Posted June 19, 2020 That's a keeper! 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
