Bone ID

[The_bro87]

This is a piece of fossilized bone I bought over the summer. It was sold as being from a centrosaurus. I understand that a perfect ID is impossible, but I was wondering if any one had an idea of what type of dinosaur it could be from, if it even is dinosaur. I was also hoping to find out what type of bone it is. It had an interesting shape to it so I was hoping if nothing else, where in the skeleton it could have been from. It says it’s from the Judith River formation, and the only locality given is eastern Montana. Again I don’t think it’s possible to tell exactly what it’s from, I was just hoping for some general description.

Yeah you can’t get a positive ID unless it was found with other bones there are identifyable so unless it was found with bones that get be identified as centrosaurus it Is unknown.
