That’s a pretty piece! Does anyone know how these ammonite cross sections contain crystallized portions? How do sellers know which fossils to cut and which not to? Sorry to hijack the post lol

Half a amminite shell! Wonderful!!!!!!!👍👍👍

@alex-stone If the excavator finds a decent specimen, they can cut and polish ammonite shells and send them to the sellers. Small crystals are probably where, during fossilization, the ammonite fossil came in contact with something like pyrite, and they kind of mix as the shell turns into rock. We observe this in dinosaur bones as well.
