Aust Cliff Bone

[fossil_sea_urchin]

I recently found this bone at Aust Cliff. When I was removing it from the matrix the bone broke into many small sections as well as two larger sections. In the dome shaped display there're the fragments that broke off, in the low quality blurry picture there is the matrix and the other one is the two large fragments. Can anyone ID the bone, thanks in advance.

I am afraid I can't take any other pictures of the bone because it is too fragile.

If complete, size would be 5.5cm?

Ichthyosaur and plesiosaur are the most likely candidates in the Rhaetian bone beds at Aust, but other creatures are present too. 

It isn't possible to tell from this piece, or most of the fragments found there, I'm afraid.

Would It have identifiable if I did not break it?

I don't think so, no.

@Tidgy's Dad is right - plesiosaur and ichthyosaur are the most likely candidates; I would lean towards a plesiosaur podial..

This book might be helpful for better ID - "Fossils of the Rhaetian Penarth Group" (edited by Andrew Swift and David Martill)

Cool find, whatever it is
