Araxoceratinae are ceratitoid ammonoids that characterize the
 restricted marine facies of the Upper Permian Dzhulfian Stage.
 Representatives of the ancestral genera Kingoceras and  Eoaraxoceras
 are abundant in the post-Guadalupian upper La Colorada beds of
 Coahuila, Mexico.  Both genera from the Araxoceras beds of Abadeh,
 central Iran, which can be correlated in turn with the type Dzhulf'ian of
 the Araxes River valley, are described.  Agreement on the precise
 definition of the Dzhulfian is yet to be achieved, but it is concluded
 that the Dzhulf'ian Stage can be defined to succeed the Guadalupian
 without major overlap er omission.  Eoaraxoceras robustum is
 proposed as a new species from central Iran.
