What species is this bone from?

I found a rib outside on the sidewalk across the street from my house. I asked about it a couple of days ago and the answers said it's either from a butchered piece of meat or was dragged there by a wild animal. Now I want to know what species of animal it came from. I know ribs are hard to differentiate but a rough guess would help. Pics next to an iPhone and a quarter for size comparison:

HOG… Of course it was butchered… See the fing SAWN end? Some slob tossed a porkchop.
