Roger I am not very firm on Triassic gastropods. You can look here. Maybe you will find a similar one.

Thanks, Andreas. I'd forgotten about that.

Update.

 

I settled in the end for an id of Loxonema sp. for that gastropod which I thought was an ammonite.

Terrific finds.

i'm fascinated by Triassic cephalopods and the Jurassic Atractites is also of great interest. 

Marvelous.

That's an incredible collection, Roger. Congrats. The colors are exquisite and those multiblock pieces truly impressive. Now that I've visited Fossil Hill in Nevada I have my own collection of Middle Triassic ammonoids including two Arcestes. Yours, though take my breath away. I also collected a small Atractites. Aren't they a kind of belemnite?

Yes, that 40-ammonite block is an incredible display block but I like that Arcestes sp. and Sandlingites matrix piece too.  A nice association Gery would like.

You could think that these creatures were somehow related to the belemnitidae, but their classification still appears to be somewhat uncertain:

They are classified presently under the order Aulacocerida, which is assumed to have later given rise to the belemnites. It's also a little confusing, since they are often classified under the superorder Belemnoidea.

Very nice finds! Thanks for sharing them with us

I have no idea how I missed this the first time around!

I'm glad it popped up again in my feed. 

Awesome finds and report, Roger!
