Ichthyosaur vertebra?

[D.R. Johnson]

Hi. I'm currently on holiday in Lyme Regis, Dorset, England and I have found this vertebrae on the beech. It's maybe 1.5cm in diameter. I believe it to be ichteosaur but I was wondering if anyone could clarify? Also, it appears to be missing a portion, would this likely have occurred pre or post fossilisation?

I think it's a rather battered icthyosaur vertebra. 

It looks water worn so much of the damage is probably erosional.

Yeah, it was near the sea shore so I guess it's been tossed in the waves for quite some time. Thanks for the info.
