aldo66 Posted August 14, 2022 Share Posted August 14, 2022 Sorry but for my part I think of a "normal" flint fracture of which we see the superimposed layers . I may be wrong! Link to comment Share on other sites More sharing options...
Rockwood Posted August 14, 2022 Share Posted August 14, 2022 This doesn't look like wood to me, but the layering may indicate another fossil. A stromatoporoid perhaps ? Link to comment Share on other sites More sharing options...
fossilus Posted August 14, 2022 Share Posted August 14, 2022 Try googling banded chert or banded flint. 1 Link to comment Share on other sites More sharing options...
