Pyrites fossil

[D.R. Johnson]

Can anyone identify this? I found it a few years ago on either Lyme Regis or Charmouth Beach, England. I believe it is preserved in pyrite and it is very smooth and symmetrical. I've asked others before but as of yet no one has identified it? I wondered if it was something to do with an ammonite as I often find them preserved in pyrite...

Welcome to the Forum!
It looks like a "cat's paw" - ammonite chamber.

Thank for the welcome.

So its a chamber which has been smashed out of a large ammonite shell?
