SnowTulip Posted June 22, 2022 Share Posted June 22, 2022 (edited) Found in Dahlonega, Georgia. Original origin (if different) unknown. Before I realized it was a fossil, I had aggressively scrubbed the stone with a denture brush in hopes of cleaning off the deep dirt stains. It worked, but I'm not sure if it damaged it at all. It doesn't look noticeably damaged, if it is, but I figured I'd bring it up. This rock is *most likely?* limestone & quartz but I'm not terribly confident in that answer. Any help GREATLY appreciated!! The fossil appears to be a mix of star shaped and column shaped indents, with what appear to be shells as well. There may be more (as there are a lot of similar indents that look more like closely packed dots) but I'm not sure. P.S.: If anyone has tips to safely remove the iron stains, let me know! I'd rather preserve the fossil than remove the iron, but I figured I might ask. Edited June 22, 2022 by SnowTulip Additional Info 1 Link to comment Share on other sites More sharing options...

jikohr Posted June 23, 2022 Share Posted June 23, 2022 Why get rid of the iron? It adds color! Also yeah, fossil coral with a few fossil bivalves. Link to comment Share on other sites More sharing options...
Ludwigia Posted June 23, 2022 Share Posted June 23, 2022 I agree with coral, but the mineral is in all likelihood calcite. Just drip a bit of vinegar essence on an unobtrusive part. If it bubbles a bit, then it's calcite. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

I put some white vinegar on a Q-Tip and put it on a part of the mineral I definitely scrubbed before and nothing happened. Did I do it right or does that mean it's not calcite?

Ludwigia Posted June 23, 2022 Share Posted June 23, 2022 White vinegar isn't really strong enough. Try a bit of diluted muriatic acid. If it still doesn't bubble, then you've probably got quartz.
