    It has the charicteristics of a horse, but I am not convinced it's from the ice age.  The fossils in Wigan are all carboniferous in age.  When you said about that brook, did you mean a stream that was called the brook or just a brook?  I the actual stream called the brook has ice age fossils, but not any brook.  I personally think it's modern.

        I don't know enough about vertebrate fossils to comment on what type of animal this bone came from.

         

        But about bone in general, I would say that:

        - if it floats it is probably not fossil

        - if (using a hand lens) the cells are empty, it is probably not fossil

          (you need a broken section so you can see the inside, not the surface)

        - if it sounds like rock when you hit it with a hammer, it is probably fossil

        - if you can scratch it with a knife, it is probably not fossil

        I have looked at smithy brook on the internet and it said you can find coal there.  Coal takes millions of years to form.  Any river contains bones, but they are not necessarily a fossil or a sub-fossil.  I once found a cow rib in a creek near to where I live but it was modern (I just threw it back in the stream.)  I can't see how you can find carboniferous fossils on land and ice age fossils in a stream.  Also, if you can find coal in smithy brook the fossils must also be a few hundred million years old, and not thowsands of years old.

      OK, that suggests it is rock - so it may be a fossil.

      But it could also be just a bone-shaped piece of rock (some flints are often mistaken for fossils bones just because of their shape).

       

      You need to see if:

      - one or both ends has the proper shape for a bone (and to do that, you's need to have an idea of what animal might be involved - something I can't help you with)

      - there is any cellular structure inside

         (this page shows a photo of that in a non-fossil bone)

         remember that the cells would be filled with minerals, so they would not be as obvious as in that photo

          (the specimens here show cellular structure fantasticly well - in multicoloured agate)

      Can you post a close-up photo of the holey part?

       

      An aurochs bone is a possibility, but it doubt it would be old enough to be fossilized, yet I would be surprised to find bone that hard. Does it float in water?
