That is a tough call. The flat look in the way it is cracked (delaminated?) is odd. I think it is bone though.

without fine structure pics not easy to say. Looks more like bone than non-fossil rock for me

I agree, the surface texture looks more like cortical bone than stone. And the scratches on top kind of remind me of cut-marks, which, depending on the ages of the material found at your specific find locality allowing for this possibility, might indicate butchering. That, at least, is what it looks like to me. Very interesting piece...!
