davidduarte Posted January 19, 2019 Share Posted January 19, 2019 Dear friends, I've met a very nice man that has kept a stone very well hidden as he thinks that it could have some value. I don't understand what it is, but it came into my mind that it can be a fossil. Can you help to indentify it? Thank you very much. Best regards, David Duarte Link to comment Share on other sites More sharing options...

Al Tahan Posted January 19, 2019 Share Posted January 19, 2019 I don’t really see anything that would scream a fossil. If it is a fossil it would be a stromatolite but I don’t think that’s what you have. It looks a lot like a concretion rich in iron. Almost has the look of the “banded iron formation” Do you know where it is from? Al 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted January 19, 2019 Share Posted January 19, 2019 This looks non fossil to me. Mineral of some sort, I would guess. @ynot Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Rockwood Posted January 19, 2019 Share Posted January 19, 2019 It's easier for me to imagine this pattern precipitating from solution so I'm going with igneous on this one. Link to comment Share on other sites More sharing options...
davidduarte Posted January 19, 2019 Author Share Posted January 19, 2019 I think you are right, it seems like iron that melted at the surface. I'll try to get some more details. Link to comment Share on other sites More sharing options...
