Hello Tobi,
Thank you for your nice comment about the ammolite. If I remember correctly, the dealer that I bought this from told me that the ammolites are coated with a clear epoxy resin.
Don

A really lovely specimen, along with some great photos.
I have often considered uploading a few fossil photos but I do not know if they would be considered minerals. I know they are composed of rock and Calcite.
Anyway a fine contribution - keep up the good work.

Thank you for your nice comment, Silvia. The ammonite shell has calcium carbonate in the form of aragonite and calcite.
Regards,
Don
