Is this a Fossil?

[Moon Fossil]

I walked for some way across Southport beach in Northwest England, after the tide had gone out.  I had originally gone there to try to locate some interesting items like shells or stones and I picked up a hand-full.  However, I had forgotten about my trip and my finds, until a few weeks ago when I relocated the items.  This particular item (pictured) is one that caught my attention the most.  On close inspection, the item contains many holes; is dark grey in colour and has white stripes that appear to embrace the stone/fossil.  Recently, my imagination has told me that this item could be a fossilized bird embryo, since I can see slight indications of skeletal bird-leg appearance, with perhaps some kind of foot - and this appears as the white stripes embracing the dark grey.  However, I actually have no educated clue as to what this item is but I will be grateful for some help towards its' identification.

It might be something fossil, but from these blurry pictures it looks more like metamorphic rock.
