Can anyone identify these carved bones?

I won these carved bones on eBay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=13765&item=160011733471 and incoporated them into a necklace to wear (though some might find this sacroligous)

Anyone have any ideas as what they are? They certainly are not chicken bones, maybe pig? Or human hand bones......:o

BTW the pix on the eBay listing are much better. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=13765&item=160011733471

THANX!

I'm guessing they're pig bones.

Look at the front "fore arm" on this skeleton.

Ahh yes I can see that they could be that. They are quite old looking from the patina on them does anyone have a clue about these where they might be from or ANYTHING?
