Ichthyosaur bone concretion ?

[Crann]

Hi, opened this up and found this bone inside, ichthyosaurs are common in the Whitby area, anyone seen a similar shape and could ID it at all ? Thanks.

My guess is 'rib', but no idea as to what species?  Not sure if that can even be id'ed?

Hi.  I think that's a Gyrosteus mirabilis fish bone.  Well done.

I'm not seeing bone structure. It may be wishful thinking, but I see coprolite.

I think I found some coprolite with little fish bones in too.
