Jurassic Ammonite from.., Earth

[rocket]

I have got an ammonite with an old collection, but, where does it come from and whats the name...? I am sure it is a middle european one, france or southern germany. And think I have seen one like this many years ago, but..., forgot the name (might be something like Hecticoceras, but it does not fit perfect). Might be someone can support with the determination, this would really help a lot. thanks!
