Hypowaagenia? bodenbenderi (Behrendsen): A rare aspidoceratid ammonite from the Tithonian of the Neuquén Basin, Argentina

Abstract

Among the ammonite collection from the Neuquén and Mendoza provinces made by G. Bodenbender, stands Aspidoceras bodenbenderi Behrendsen. This rare aspidoceratid is assigned to the lower Alternans Zone because of the associated Parodontoceras calistoides (Behrendsen), and can be most likely attributed to the recently established genus Hypowaagenia Schweigert & Schlampp.
