France pyrite ammonite id

[Raptor9468]

I was given this ammonite from France as a gift,a small part is gone outside.Does anyone know what species or age this is? Sorry but I dont have the formations and age.

 

Also a short question,if I put it in a bag would it prevent pyrite disease?

Dactylioceras? 

 

EDIT: RE: Pyrite disease - putting it in an airtight bag or container with a dessicant package would be the best way to store it, in my opinion. 

If you do a Forum search for Pyrite disease, some young members a number of years ago, did an experiment with different coatings. 

It was an interesting post.

It could be a Catacoeloceras from middle toarcian but without more informations it's difficult to be sure

I got my magnifier and found some patterns on it

That would be my guess as well, but like you say, it's not for certain without the necessary details on location and stratigraphy.

Strenoceras bajocense is known from the bajocian
