NMSS21 Posted April 11, 2018 Share Posted April 11, 2018 I found this 40 lb chunk of what looks to be oolitic chert with some agate tubes running through it in east-central Minnesota while out agate hunting. Maybe it's considered a cold water agate, but I'm not really sure what that truly means anyways. Either way, I was wondering if there is something more to this structure besides oolites. Maybe some kind of coral or other reef building organism? Any more information would be great. Thanks! Link to comment Share on other sites More sharing options...
Raggedy Man Posted April 11, 2018 Share Posted April 11, 2018 Looks like chalcedony/agate to me. ...I'm back. Link to comment Share on other sites More sharing options...
ynot Posted April 11, 2018 Share Posted April 11, 2018 Welcome to TFF! I see nothing that looks fossil in this agate. Nice piece though. Darwin said: " Man sprang from monkeys."

FossilSniper Posted April 11, 2018 Share Posted April 11, 2018 Here's what I can see... I'm really just guessing, but take another look and see if there was anything there! I find tons of imprints in rocks just like this all the time! (I'm in Fairborn, Ohio) Try looking into the little circular holes that I pointed out... maybe the hole was left by a coral? Who knows? You're welcome, if anything is indeed there Link to comment Share on other sites More sharing options...
Fossildude19 Posted April 12, 2018 Share Posted April 12, 2018 The whole thing looks geological, to me. No fossils.
