Aspidoceratinae

Physodoceras sp., from here.

Belongs within: Aspidoceratidae.

The Aspidoceratinae are a group of ammonites known from the Middle and Upper Jurassic, members of which possess laevaptychi (aptychi that are smooth on the exterior surface except for some very weak pustules, and bearing concentric growth lines on the interior surface) (Enseger & Keupp 2002).
