grampa dino....excellent colours.... Its nice to see the base nodes as well for some form of protective spines that this species had.... They must of been easy prey food for most predators... I'll tell you what I find intresting, if they were anatomically similar to todays modern nautilus, (as a general comparison) ive seen some pretty narrow species of ammonite shell, that would be a seriously tight fit to live in...

Thanks: I have heard those protective spines could be more like very stiff hair or barbs protruding some distance from the shell.

That would make him a little harder to serve for supper. I to have read or heard that they are related to the modern nautilus.

JohnJ..... wow they are 'Tiny'..... If Dans having a rough fossil month, maybe hes not getting close enough to the ground to find the fossils like you do, and while he's down there maybe he could pray for a find lol.....

Grampa dino.... If you look at (I think page 2) of this thread, theres some protective ammonite spines preserved in pyrite.....

Nice fossils everyone well done.... :D

I bought this at a club auction a few years ago. Ammonite and imprint of same. From the personal collection of a former fossil curator at the Houston Museum of Natural History. It is put away at the moment, so I don't know the relevant info on it.

post-534-12577868843279_thumb.jpg

Wow :o , look at the gold color it made. That is a very impressive fossil! :)

Looking for Oregon transparent Aturia angustata now. PM me if you got any for sale.

I'm looking for other COILED nautiloids too! Anyone have any nautiloid before jurassic period?

this specimen comes from the lower jurassic (Lias delta) clays of Unterstürmig / Buttenheim in Bavaria (Germany). The golden colour derives from a treatment with a brass-brush. My attached picture shows some different kinds of conservation of ammonites (Pleuroceras sp. / Amaltheus sp.) from this site.

The white type of conservation (the ammonite in the middle) is most common, also for most completely pyritized ammonites. I personally like this natural (white) state the most, because it makes a good contrast to the dark clays (second picture). Some finds even show parts of the original colour pattern (see last picture).

haven't heard it but it makes sense that FeS2+ your breath would equal H2SO4 + your discomfort.

You get similar effects when cutting up raw onions.....

My small ammonites (a lot have just fallen apart since their discovery, but ive still got a few). note that one has some shell encrusted on its surface.
