Neat fossil. :)

The chambers of the shell have been replaced by crystalline growth.

Not all of them. It looks like some were replaced by sand that cemented.

I've seen some ammonites from Madagascar where every chamber is packed full of calcite crystals.

They're most impressive - and waaayyy too expensive. :lol:
