My son found a fossil on the beach at the foot of the cliff face at Robin Hoods Bay in the UK. It is definitely a fossilized piece of wood, but we would like to know what type, and also if it was possibly a tool of some kind, maybe a pounding stick? It fits beautifully in the hand and appears to be moulded to feel that way, there are obvious signs of wear in shape and patina, and both ends appear to my eyes to be beaten flat through wear rather than a break. I would be interested to hear anybody's thoughts on this. A bit of a mystery for us. Thanks.

    $\begingroup$ Not enough information to confirm it is petrified wood but the shape is very common for a naturally worn down piece of driftwood. $\endgroup$ – Friddy May 14 at 17:28
  • $\begingroup$ @Friddy is right what you have there is a common piece of driftwood,does it float in salt water if it does it is not petrified wood.you can take a look here en.wikipedia.org/wiki/Petrified_wood to learn more abou petrified wood $\endgroup$ – trond hansen May 14 at 19:30
  • $\begingroup$ @trondhansen I guess it might still sink if it is waterlogged, but petrified wood is more than twice as dense, 2.58-2.91. Peter should be able to tell the difference. $\endgroup$ – Keith McClary May 15 at 5:20
  • $\begingroup$ You observe wear and then speculate about it being a human tool. 'Sorry to disappoint you, but Occams razor suggests it's 'just' a piece of driftwood. $\endgroup$ – Jan Doggen May 15 at 8:27
  • $\begingroup$ @KeithMcClary you are right,but if it floats it is definitly not petrified,sorry for not beeing clear on this. $\endgroup$ – trond hansen May 15 at 9:52
