Birddogski Posted November 22, 2016 Share Posted November 22, 2016 What is this?? Found in north central mn lake. Sure looks like coral. Link to comment Share on other sites More sharing options...
tmaier Posted November 22, 2016 Share Posted November 22, 2016 Birddogski, I think your object is a mineral concretion. They can grow in high mineral areas and have this wild growth pattern. Let other people comment. Link to comment Share on other sites More sharing options...
Fossildude19 Posted November 22, 2016 Share Posted November 22, 2016 Welcome to the Forum. I moved your post to it's own topic. More eyes on it this way. I agree with tmaier. Looks mineral to me, as well. Can you get another shot like # 1, but more in focus?

fifbrindacier Posted November 22, 2016 Share Posted November 22, 2016 I agree for the ID of mineral concretion. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

minnbuckeye Posted November 22, 2016 Share Posted November 22, 2016 The bedrock structure of your area is paleoproterozoic so unlikely to produce much unless glaciation brought in something. The rock looks geologic to me. Nice Smallies!!!! From the mighty Mississippi? Link to comment Share on other sites More sharing options...
FossilDAWG Posted November 22, 2016 Share Posted November 22, 2016 Coral should have corallites, the "holes" or sections where individual polyps (coral animals) lived. These structures are absent in your specimen. Don Link to comment Share on other sites More sharing options...
Kane Posted November 22, 2016 Share Posted November 22, 2016 There might be something fossiliferous in this, but at a distance it simply looks "weathered." Are there any unique features in this piece? As @FossilDAWG noted, if it were coral, we'd see some corallites. Zoom in on anything that looks unique in terms of a feature. Look at any colouration or shapes that are not in conformity with the rest of the rock.
