dhiggi Posted August 22, 2020 Share Posted August 22, 2020 Found this yesterday on the foreshore at Redcliff Point, Dorset. It’s mineralised; feels like rock and sounds like rock when tapped against another. Could it be a piece of fossilised wood, or even rib bone, or has some other process caused the appearance?

TqB Posted August 22, 2020 Share Posted August 22, 2020 The carbonisation says it's fossil wood, though I don't know why some is carbonised and some not - maybe one of the plant guys could help. Possibly a sediment filled pith core though it seems to have some grain structure. 2 Tarquin Link to comment Share on other sites More sharing options...
dhiggi Posted August 22, 2020 Author Share Posted August 22, 2020 I was leaning towards wood as we’d seen quite a bit in larger rocks, but puzzled by the different materials 1 Link to comment Share on other sites More sharing options...

Here is an example from my area (Miocene), see page 14: Fossil wood (pdf, external site, ca. 4 MB) Interior silicified, exterior coalified. In polished section you can see continuous wood grain between the two parts. Franz Bernhard 2 Link to comment Share on other sites More sharing options...
