What is this? Fossilised wood?

This was dredged from the South Coast and I am trying to ID it from images. The finders describe it as fossilised wood. Any thoughts? Many thanks.

    From images, it is difficult.

    There seems to be a dark 'skin' layer, but that impression is confused by a few little 'windows' in the pale face (which may be a vein) which seem to show the dark material existing deeper within as well.

     

    I would advise that from images, a reliable ID is unlikely.

    The object really needs to be inspected in the hand and under a microscope. If it was dredged from recent deposits, we'd hope to find some cellular structure and perhaps surface texture indicative of wood/bark.


    If at all feasible, I advise taking or sending it to the IAS (Identification and Advisory Service), Angela Marmont Centre, Natural History Museum.

    Hi gingason

    I can also see the dark skin layer around the surface that looks like bark but the similaraty seems to stop there, although variable preservation could have preserved the specimen in many ways.

    Looks a bit like one of those fungi you see growing from tree trunks.
