Macro & Micro

The larger ammonite is probably Ludwigia (Ludwigia) bradfordensis deleta and the smaller one the microconch Ludwigia (Pseudographoceras) umbilicata. I can't say if they belong together as man and wife, since I still need to further research the subject of dimorphism within this family. Bradfordensis zone, Upper Aalenian. Found in the Wutach Valley.
