BLT Posted June 30, 2018 Share Posted June 30, 2018 Hello! I am wondering if this might be coral? It was found in a creek in middle Tennessee. Link to comment Share on other sites More sharing options...
ynot Posted June 30, 2018 Share Posted June 30, 2018 I see nothing to indicate coral, it looks like one of those "blown up fossil" type geodes.. Google search for "midwestern type sedimentary geodes". 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough." My Fossil collection - My Mineral collection My favorite thread on TFF. Link to comment Share on other sites More sharing options...

Bronzviking Posted June 30, 2018 Share Posted June 30, 2018 I've found many corals in Florida and I have to agree with ynot that I don't see coral. It does look like it has botryoidal (grape-like) bubbles in it. Try image google search "rough brown chalcedony". Link to comment Share on other sites More sharing options...
BLT Posted June 30, 2018 Author Share Posted June 30, 2018 Thanks! @Bronzviking I just googled “rough brown chalcedony”. Am I correct in assuming that is also what the attached picture would be? Link to comment Share on other sites More sharing options...
Bronzviking Posted June 30, 2018 Share Posted June 30, 2018 It appears to be Chalcedony a microcrystalline type of quartz occurring in several different forms, including onyx, agate, and jasper. Nice find! Link to comment Share on other sites More sharing options...
