Theropod dinosaur vertebra?

Hello. I got this dinosaur vertebra from Nemegt Formation. Size 7cm long. It seems like a theropod caudal vertebra. But I don't know exactly what species it is.

I saw this for sale on an auction site, it looks very thin from above and looks as if it has had some amount of restoration. 

We will see what @Troodon thinks.

I don't know much about this formation but it looks similar to Spinosaurus vertebrae, so I guess Deinocheirus would be a good candidate?

Theropod seems plausible and it looks like dorsal.

It does also bear some resemblance to Spinosaurid dorsals.

To me it looks like a large theropod I agree with dinofossilsUk it could be Deinocheirus

Agree with the others has that Theropod look.  I really think you need a paleontologist  that is familiar with that unit for an answer.  Very little to compare against or is published.

Here is a dorsal of an  Alioramus

My paleontologist friend said this is a ornithomimid dinosaur vertebra like Gallimimus... I thought it was Tyrannosaur vertebra...

I agree. Ornithomimid caudal vertebra. Likely Gallimimus bullatus.
