gdsfossil Posted April 20, 2022 Share Posted April 20, 2022 Going through Permian matrix. We have found many teeth and other identifiable microfossils. I have also found many of these metallic looking dark rocks. Are they bone fragments, or partially melted rocks? Thank you. Link to comment Share on other sites More sharing options...

They look like pedogenic iron oxides such as hematite, goethite, and maghemite. Yours, Paul H.
