Nrudolph Posted January 18, 2019 Share Posted January 18, 2019 Appears to be mineral deposits of some sort, however the spiral shape of the mineral makes it look fossily. Matrix is 4"x4"x6", very dense, hardness around 5. Found in a river near Grand Cache, Alberta. Any ideas? 1 Link to comment Share on other sites More sharing options...
fifbrindacier Posted January 18, 2019 Share Posted January 18, 2019 Yes, fossils of shells in cross section. 4 "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

I agree with fragments and sectioned views of thick walled bivalves or brachiopods. 1 Link to comment Share on other sites More sharing options...
