Possible crab fossil?

[John_smith]

Can anyone ID this please? Found in Surrey, England on farmland/woodland.

Possibly the underside of a crab?

 

Thanks

Not a crab, this is just a rock unfortunately.

I can see what you are thinking might be a crab (in the first photo, left hand side), but I am pretty sure it is worn section through a snail.

the wear has produced cross sections through the individual? elements. Hopefully someone form the UK will recognize this.
