I recently found this in the Hell Creek

formation in Glendive, Montana. I've been told it's rex, deinosuchus and edmontosaurus lol. Any help is greatly appreciated!

 

Thank you in advance!

How big is it? 

I don't think it's tyrannosaur. 

I don't have a ruler at the second but ballpark 6 inches tall and 4 across

I am not familiar with such large critters that have such round ball and socket vertebral ends in the HC/Lance.

Nice find!

 

It really does look like a huge Crocodyliform vert. Here's an article with some good pics of a Deinosuchus vert about that size. It also has the huge ball and deep socket.

Aside from that, and this is going to sound insane, but could it be Mosasaur? Here's a link to an article talking about some recent discoveries of some big ones in Hell Creek.

First, the word for a singular "backbone" is "vertebra"; vertebrate is a word that encompasses all organisms with a spine - technically the title isn't wrong, but I believe the former is what you meant.

 

I believe Occam's razor would favor the simpler ID of a hadrosaurid cervical vertebra.

I've never dug a Hadro cervical vert, I didnt realize they were opisthocoelous.
