What ichthyosaur bone is this?

[LiamL]

I think one is a rib, but i'm not sure about the other bits, cheers.

Hi, 

 

The long bone in the centre does seem likely to be a rib, and I can see what may be part of a vertebra in the top right, but that's about as far as I can distinguish. 

 

It may be worth posting closer up images of the areas you're unsure of.

Thats what i thought, i'm wondering about the thing next to the vertebra and at the bottom left.

that's a complete neural spine

Maybe @JohnBrewer will know.

As Paul says that’s a complete neural arch and a very nice one too!

I agree with the others Rib, neural arch and 2 x partial vertebrae.

Yup on the neural spine.  My experience is that they fall off the centrum pretty readily.

Can’t say I’ve even seen one on a centrum except in museums and I guess that would have probably been a part of the prep.
