Keupp H., Schweigert G. (2008) Juraphyllites mimatensis (d’Orbigny, 1845) (Ammonoidea: Phylloceratida), a Tethyan immigrant in the Upper Pliensbachian of Franconia (Jurassic, Southern Germany) // Paleodiversity. Vol.1. P.133-140.

Two well-preserved small-sized specimens of phylloceratoid ammonites are reported from the Late Pliensbachian Spinatum Zone of Franconia. They are assigned to Juraphyllites (cf.) mimatensis (d’Orbigny, 1845) and regarded as Tethyan immigrants. Due to their very similar early ontogenetic stages it seems impossible to distinguish tiny juveniles of Juraphyllites mimatensis (d’Orbigny, 1845) from those of contemporaneous Meneghiniceras eximium (v. Hauer).
