Hello and a very warm welcome to The Fossil Forum from Morocco. 

That's an interesting ammonite. 

Always nice to see unusual specimens from Japan.

Hi, and welcome to the Forum.  We rarely get to see fossils from Hokkaido, although of course the area is well known.  I hope you will have more to show us!

 

I edited your title from "Ammonoid" to "ammonite", as ammonoids are a real group of cephalopods that are (perhaps subtly) different from true ammonites, so your title was a bit confusing.  I also added "heteromorph" as a tag to make your very nice ammonite easier to search for.  I hope you do not mind.

Very nice find. Welcome to the forum.

Interesting!

The Hyphantoceras we get over here on Vancouver Island look rather different (more corkscrew-shaped), though the same age.

Got any more pics, from different angles?
