Identify dino bones

[AranHao]

In fact, I found that bones are much more difficult to identify than teeth. I regret buying dinosaur bones. I have three materials here for you to give some suggestions. I hope to get the correct identification. After all, it's no good to cheat yourself.

Thank you for any comments

（The following information is the only one I know. There is always no location ）

 

Hadrosaurs vertebral column

From Judith River FM Montana

Spinosaurus

From Kemkem Group 

Camptosaurus(Phalanges?)

Jurassic Age 

Morrison FM Wyoming

[Troodon]

When taking pictures of bones for identification I need straight in images of the sides, bottom and ends.  No obtuse/angle photos.  So will need those for the vertebrae

 

The Morrison toe bone looks like it's from an Ornithopod possibly Camptosaurus.

@TroodonThanks for the response,I added new photos

[Troodon]

Thank you for the additional photos, perfect.

First

I dont think its a hadrosaur.  The shape of the ends are all wrong as well as the texture of the sides.

Second

It's not Spinosaurid looks more marine like a plesiosaur 

 

@LordTrilobiteany thoughts on these two?

Thanks for the response. What do you think the first one will belong to？

Agree, not hadrosaur. It's a distal caudal vert. Could be ceratopsian maybe?
 

2
Absolutely not Spinosaurus. Like Troodon said, likely plesiosaur.
It's also not from Kem Kem but from the phosphate beds in Morocco. The colours are quite distinct. Nice vert though.

3
The phalanx does look like it might be from an ornithopod.

I thought of that but ceratopsian caudal centrums are typically round.   I even wondered if it was dinosaurian with that fibrous bone

Do you have any ideas? What do you lean towards ?

[Troodon]

I would say if I knew.  ????

hhhhhhhhh, thanks again

@TroodonI found this figure. Can it be D, E, F？（flat round shape）

 

I understand that ceratopsian are typically round, so what makes you recognize them as thescelosaurus? Is it because of its position？Haha, because I think it is round enough

[Troodon]

 Grooves are present on the perimeter of both inside edges of the centrum.  That is typical of Thescelosaurus and not seen on ceratopsian..  The centrum is also not round, its dorsal surface from side to side is fairly flat.   These are subtle differences but important.

 

Here is a photo of Thescelosaurus vertebrae.  You can see the grooves
