Ammonite ID

[JohnBrewer]

Hello forumites

 

Can’t seem to find an id on this ammo. I guess I might need to prep more to see the keel but it’s pretty fragile. Could Paraloid it I guess.

Thank you. That is looking good!

@JohnBrewer I would rather tend to Kosmoceras.

I would have expected that Kosmoceras had more spines? But there is indeed a lot of variation in those ammonites.

 

The keel will have to be preppes out to be sure I think.

It depends on the species. You're right about prepping out the keel. Quenstedoceras has more rounded whorls, which is why I still tend to Kosmoceras.

I did wonder if that would be the case. The matrix is very soft, I hope the ammo isn't as soft. Pin vice I think for this one.

 

Thanks guys.
