Hunstanton fossil find

[Nicole99]

Hi all, I was hoping for some help with this. Is it a fossil? It’s quite worn so I’m not expecting a detailed ID but some suggestions would be fantastic. 
I found it at Hunstanton which is chalk or Cretaceous age. 
I’ve also found lots of brachiopods and echinoids at this locality.

It is a fossil.

Let's wait for the specilists to tell more..

It's a serpulid worm tube.

[Ludwigia]

Agreed.
