Enay R., Boughdiri M., Le Hegarat G. (1998) Kilianites gen. nov., Himalayitidae (Ammonitina) nouveau du Berriasien de la région de Cabra (province de Cordoba, SE Espagne): descendance de Protacanthodiscus // Compte Rendues de la Academie des Sciences/ Elsevier, Paris. Sciences de la Terre et des Planétes, 327. Pp. 549-554.

A new ammonite genus of the himalayitids is described for the group of Hoplites bergeroni Kilian, 1889. Kilianites gen. nov. is only known by its macroconchs (M), until now ascribed to Protacanthodiscus, macroconch of Durangites (pars), or/and Neocosmoceras. The relationships with Protacanthodiscus and Neocosmoceras are discussed, taking into account characters of the ontogenesis and stratigraphic position: Kilianites gen. nov., of the Berriasian Euxinus Zone, jacobi Subzone (= calpionellids B zone) succeeds the Durangites-Protacanthodiscus acme in the Upper Tithonian Durangites Zone (= A2 and A3 calpionellids subzones).
