I think, ... in Nautilus, the crenulate keel of the ventral ornamentation is not present, but in Ammonite could be there (not in all cases), so, I'll go with Ammonite in the distinguishing character.

We need better pictures that show more distinguishing features in order to decide properly. Everything else is guesswork at this point. I also tend more towards ammonite.
