If my memory serves me, here I see the natural coloring of the shells, which is not often found in illustrations!

No, but im planning to make a taxonomic chart showing all known cephalopods with color markings, all to scale. so stay tuned!

Ok, sooo does this include ammonites, and are you doing individual species?

Yea it does. I'm trying to stay as true to the evidence so the speculation is down to a minimum. I have a list of about 120 species from which I know the color patterns. They include a dozen or two ammonites. Sadly this will not be a complete record of all known ammonite color preservation because I don't have access to many old papers or to unpublished material.

Very nice work.
Have you found any of these species as fossils personally? Iβm into ammonites or anything cephalopod related, baculites, Orthoceras, nautili and the likes. I have not seen theΒ Pragmoceras or the Ptenocetas. I didnβt even know such forms existed. So you have increased my awareness and knowledge. Theyβre very cool.
I also have a fascination with echinoderms. All have been spurred on by personal finds.

Thanks!! I thing I have found an annulated orthoceras, but I don't know the species.. in any case fossils that preserve the coloration are exceedingly rare. And my chart is based on published data not speculation.btw there is a paper published on the color patterns of Mississippian blastoids that might interest you! and reports on a stripy pattern on crinoid arms too!

There are Mississippian formations about 5-6 hours away. My dad lives near some. I do love echinoderms and blastoids are in that group. Someone from TFF sent me 2 blastoids for Christmas. Theyβre very cool.
I have found some Cretaceous oysters and clams that had their original coloring. Most were quite fragile though. I was shocked to find them like that. Itβs very rare around here.
