What kind of animal do you think this is???

I found this wonderful skull the other day.
It's small as you can see it fits in my hand.
I LOVE skulls. I'm not sure why...but to me they are such great works of art.
I don't know what kind of animal this is....
Is it a head...or maybe it's a foot???
The teeth or claws, though go straight out.
And there is that empty space where two more claws or teeth go....
It's a mystery to me.
Do you know this animal????
