What is this pyritized ammonite species?

[Danusorn Chu]

This fossil was found at Liesberg, Switzerland.

It looks like Psiloceras mixed with Hildoceras.

This fossil was found by my cousin who lives at Switzerland.

It's beautiful whatever it is!  Do you know measurements?

[Danusorn Chu]

The size is 11 mm

[Ludwigia]

I would say that that is the inner whorls of Hildoceras. Different genera don't "mix".

[Danusorn Chu]

I think so, at first I thought it was a psiloceras, but in the close range, I saw patterns like hildoceras on the shell.

I had a search again, the ammonite is Hecticoceras suevum. I found this species from this website. Ammonites Jean-Claude Bertin (free.fr)
