Can someone help me identify this fossil?

I found this Fossil a few weeks ago in Casper Wyoming. I dont have the exact measurments, but if i had to guess i would say that the central part of the fossil was 12 inches wide by 8 inches deep. The plate that extends from it is also about 10 inches wide and 4 inches deep.It probably weighs about 30 lbs. My guess is that it is a vertebrae. Can anyone help?

I took these pics with my phone so they arent that clear. Heres another pic of the suspected large vertebrae

Oh yes! I am quite sure this is a dino's vertebra -

How exciting you keep finding all these interesting things

Copper- How many animals do you know of with bones that size? lol Yes! You are correct! That is a dinosaur vertebra. Good eye!!

We've already answered that question. It's a Dinosaur vertebrae.

i was trying to get more info than that. I hope by giving better pics and the lacation that someone might be able to help narrow down what kind of animal it came from

Oooh....sorry. Maybe you conuld've been more specific. I think that's a smart idea, though.
