Is it possible to identify these bones?

[FrontRange]

Hello, I recently found a washout on a ranch i have permission to look for points on that has a lot fossilized bones coming out of it, I collected a bag full to try and identify them(with permission from the owner). So far I have found out that the area I found them is in the two river formation, I'm thinking they are dinosaur, is there any way to know for sure? Here are a few examples, thanks

Are you sure you don’t mean either the Judith River Formation, or Two Medicine Formation, both of which yield dinosaur and reptile bones?

Yes your right I meant to put two medicine formation, that's what got me thinking dinosaur bones.

Wish I saw this earlier, I was at Museum of the Rockies earlier today in Bozeman and would have asked the paleontologist we were watching clean fossils.
I know you San send the photos and they can try to identify them. Worth a call over there to get an email address for the right person.
As I was walking around, I was thinking it’d be awesome to stumble upon some dinosaur fossils while out point hunting.
keep us posted on what they may be.
I bet they’ll be able to identify the vertebrae at least.

I never even thought of that I'll call over there tomorrow and see what I can get figured out thank you, and I'll update as soon as I find something out.
