Little Jo visited and brought with her a 'fossil'. She is quite proud of her fossil found at her local beach. What is it? Is it set sand encasing something? I initially thought it was perhaps an old telecommunications submarine cable. Is the sand casing man made or the result of a natural process? I learnt that sharks at times attack submarine cables, and so that would explain a man made sand casing.
The camera produced some odd and uneven colours. The casing was pretty well the same colour; the dominant colour in the photos.
It seemed to have little node like spikes at the broken end.
My final thought was that it is the burnt branch of a tree and the sand was attracted to the sap when the wood was rolling around on the sea floor. Your opinions would be appreciated.
