and that makes a nice link back to the Germanonautilus beaks at the top of this thread, since they were once thought to be the beaks of Ceratites (Schmidt-Effing 1972, Mayer 1974).
 
Thanks. So, now "beaks" is under soft part preservation let's look at some soft part preservation around a beak. I interpret this as a view from beneath of a dorso-ventrally crushed nautilid. The lower image is made with my little UV lamp and is rotated 90 degrees relative to the upper image.

You can almost make out some arm molds on there. Is it just a thin film that is reflecting the UV?

Thanks for the Kummel Paper, been looking for that one. :notworth:

Although "Beaks" are actually hard parts, they are commonly found with the associated soft parts, I thought this was the best place for it. :smile:
 
A couple of close-ups. Yes, these are thin sheets of phosphate in front of the beak, with individual elongate features visible.

To help make sense of the specimen above here's Neville (after Neville Hollingworth and a day looking for Permian nautilids in the Magnesian Limestone of northern England long ago):


I've shot this from below so we can see the beak from time to time.

This is the meeting between Brutus and Neville:
