Oolites or something more?

Recommended Posts

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!

Looks like chalcedony/agate to me.

Welcome to TFF!

I see nothing that looks fossil in this agate.

Nice piece though.

I see potential bone structure, but agree that it is outweighed by evidence to the contrary.

Here's what I can see... :trilosurprise:

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 :)

The whole thing looks geological, to me. 

No fossils. :(
