I agree, that fern pattern is really nice. Many of my smaller pieces have that pattern on them after polishing.

The first one is killer!
I saw some that were collected in Glendive, Montana on my trip last weekend. A couple were almost as big as your large ones and one was irridescent.

Yep those are real Beauts! is it true that the cells are made from the critter that lived within? as I understand it, when it outgrew 1 cell it would build another. hence the pattern Ed

Boy O boy O boy. Those are amazing. I have a Baculite with the fern pattern but I never saw a fern pattern on an Ammonite and I didn't know about how they grew. adding cells as they grew. I love learning these kinds of things.
Thanks for sharing.

Very nice indeed. The pattern is called sutures.

Very cool site, thanks for that. Bookmarked it after reading the entire thing.

Thanks for that link!
I was under the impression that the suture structure of shell was what the original shell looked liked. And that the opalescence sheen was caused by the fossilization.
Guess my theory was wrong according to the article.
Anyone have any thoughts on how to best expose that suture from the hard enameled opalized sheen that’s on the shells? Some sort of light grinding, I would suppose? Thanks Ed
