Jurassic Ammonites

[Hollie Bird]

Evening everyone

 

I would much appreciate help in identifying these little ammonites preserved in pyrite. I picked them up on the shore of Portmuck Harbour which is on the Eastern Coast of Northern Ireland. 

They originate from the underlying early Jurassic Waterloo mudstone formation. 

 

Thanks for looking!

Hi,

 

Not sure but I m thinking of Beaniceras. Could you show us the keel!

It looks a little like some sort of Psiloceras?  We can ask Roger  @Ludwigia he Is the man. 
 

cheers Bobby

Keel appears to be quite smooth. 

[Ludwigia]

I would have to agree with Badeend. Probably Beaniceras.

Thank you for the ID. Much appreciated!
