Bone or rock?

I'm posting this hoping to get some input on what this is? Found it in Flagstaff AZ, thought it sort of looked like bone. It's heavy for it's size, hard and a little magnetic in that it makes the compass move. So, when I found this out was confused a bit...but then found a site (mama's minerals) where they have an story titled "The Mystery of the Magnetic Dinosaur Bones"....so? I'll post 3 photos of it, thanks everyone!
