Very small ammonite

Recommended Posts

Hello all

 

I was wondering if any of you could identify this very tiny (1mm) ammonite sitting on top of some Dactylioceras athleticum from the Jurassic of Schlaifhausen, Germany. Can this be a juvenile stage of the same species? I know nothing about the different lifestages of ammonites. 

 

Looking forward to your answers.

 

Edit: does someone knows the size of the smallest ammonite recorded?

Probably a microchonchid, rather than an ammonite.

Thank you for your answer. The right one is really similar to the fossil I have.

I'd say that this is a small ammonite as well, probably either the very inner whorls or a "baby" Dacty, although Cleviceras is also possible.
