Any idea with this?

Hi guys, would anyone know what this may be? Looks shell like to me with the same pattern of dots going the length. Thanks

Could be a really battered urchin of some kind but wait and see what others say!

Thanks, I love the mystery of things and also finding out and learning

I agree. Flint echinoid.

[abyssunder]

Yep, nice echinoid!

Thank you guys :)  now I know where to go to do some research.

I think it is an Echinocorys but I can't tell you more because it is an internal mussel without the details that allow to specify the species. However, your present shells behind are Nucella lapillus.
