Possible theropod phalange from Hell Creek

[Warbreaker]

Found this little guy in the surface float near Glendive, Mt, hell creek formation. I thought it might be a theropod phalange, but a buddy thinks it's champsosaurus. Any thoughts?

Do you have a locality where its from?

 

Might be a Digit IV-4 phalanx of an Ornithomimid.  Can you take straight in lateral views of both sides. 

 

For future posts : Your obtuse photos are not the best to ID material.  Always need straight in shots of all sides

Thanks for the advice! How are these photos?

Good thanks, I'll stay with my initial call.  Nice bone

Dang. Looking at all of these dinosaur images in these posts makes me want to find dinosaurs now. I'm neck deep in Pleistocene... but dinos....wow. Nothing like that down here. Cool stuff outta Montana.
