SilurianSalamander Posted September 13, 2022 Share Posted September 13, 2022 Found this larger chunk of rock (too hard to be modern charcoal) while sifting for microfossils. It has a metallic look to it and is fairly brittle. It was found on bradford beach on Lake Michigan and was likely eroded out of the mid Devonian Milwaukee formation which is known for its coalified trees and giant fungi. this looks like a lot of coalified wood I’ve seen pictures of, but I’m pretty new when it comes to plant fossils so this might just be mineral.

Rockwood Posted September 13, 2022 Share Posted September 13, 2022 I'm not sure I'd call it wood. Under magnification it is possible that one may find indications, but coal seems more likely to me. 1 Link to comment Share on other sites More sharing options...

Coalified wood still looks like wood only a bit harder and darker. Coal is undefined plant matter that has been compressed into an altered form. 2 1 Link to comment Share on other sites More sharing options...
JohnJ Posted September 13, 2022 Share Posted September 13, 2022 Just a photo, tip oft repeated on TFF...the combination of unstable hand held fossils and cameras result in areas of poor focus. The fine details on smaller specimens are lost in the blur of combined shaking; and often, those are the details needed to offer identification clues. You can eliminate one source of instability by placing your fossil on a solid surface. I use a kneaded artist eraser to help position items that cannot stand on their own. 1 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
