Potential T. Rex Bone?

[Tigereagle12345]

I found this bone on a fossil hunting trip in North Dakota, it was identified as a theropod, probably a T. Rex. Can anyone verify this claim?

 

Thanks for any responces!

It's a non-descript bone what features are there to say T-rex or theropod?  Location in ND?

I doubt that anybody is going to be able to give you a positive ID.  These kinds of things can belong to many possible species.  Without knowing anything about the location, formation, etc. makes it even harder to guess.  Now, that said, if this was in the Hell Creek location I'm used to working, I would probably give it a tentative rex ID based on the combination of size and its dense, almost black "glassy" appearance.

@Troodon

The bone was found near Marmath, North Dakota, on a flat area below a butte. The reasons I believe that it is a T. Rex is because it is curved on both sides which suggests that the bone may have been hollow, and because, althought it is hard to see, it has a very dense bone structure around the outside part of the bone and a very open one on the inside. (I can't seem to get any non-blury photos but most of it is completly solid exept for the middle part which is open.)

 

The blackish part is solid, the brown(In the first image) and white parts are open.

Thanks definitely HC area 

I understand your point but "may have's" and density does not do it for me, maybe others are okay with it.   We have other Tyrannosaurs and Theropods like Anzu in the HC  that have big bones so for me its indeterminate.

Ok, thanks for the information!

I would hesitate to call this anything other than "Dinosaur".  Hadrosaur leg bones can look like this from experiences.  I think there are local enough preservational differences in the Hell Creek that it could be anything big.
