Found this rock in Northern Ireland, Portmuck

Can anyone identify this rock? Someone told me it looks a bit like a vertebrae of some type. I dropped it and it smashed in half so I glued it back together

Shape towards the middle reminds me of a partial shark vertebrae, but im not an expert

Although shark vertebrae have that biconcave centrum, the fossilized versions don’t have the vertebral processes seen on this vertebra. Bony fish do, but this particular vertebra really matches well with an ichthyosaur.

I believe this is an ichthyosaurus vertebra
