The ammonite family Parahoplitidae in the Sanganeh Formation of the Kopet Dagh Basin, north-eastern Iran

Phenotypic plasticity and taxonomy of Schloenbachia varians (J. Sowerby, 1817) (Cretaceous Ammonoidea)

“…Mid-Cretaceous ammonoids are well known from Iran (Seyed-Emami 1988), having been recorded from several localities in the Koppeh Dagh Mountains, NE Iran (e.g., Seyed-Emami and Aryai 1981;Seyed-Emami et al 1984;Immel et al 1997;Raisossadat 2006;Mosavinia et al 2007). The Koppeh Dagh exposes an expanded Cretaceous succession of sedimentary rocks, ranging from the lower Lower Cretaceous (''Neocomian'') Shurijeh Formation, up to the Maastrichtian Kalat Formation.…”

Ammonite stratigraphy and the belemnite genus Hibolithes in the higher Serdj Formation (Aptian-Albian boundary interval) in north central Tunisia

“…As already stated by Szives et al (2007) the "stratigraphical distribution of Parahoplites, and also the co-occurrence with Acanthohoplites and Hypacanthoplites is problematic" and Owen (1996) states that the upper limit of Parahoplites falls together with the occurrence of Hypacanthoplites in the Late Aptian Nolaniceras nolani Zone that is debated though (Casey 1996). Szives et al (2007) suggested that Acanthohoplites, Hypacanthoplites and Parahoplites are partly cooccurring in northern Iran interpreting Raisossadat (2006). This interpretation might be partly based on general statements of ammonite occurrence but no detailed ranges are given by Raisossadat (2006).…”

“…LATIL (2011) Malgré les remarques émises ci-avant, en l'absence de cette révision taxonomique du genre Hypacanthoplites et en raison de l'impossibilité d'observer sur nos exemplaires les états ontogénétiques juvéniles, nous avons, dans ce travail, opté pour une acception du genre Hypacanthoplites dans son sens le plus large. C'est généralement cette conception qui est adoptée jusqu'à présent par de nombreux auteurs (CASEY, 1950(CASEY, , 1961(CASEY, , 1965FÖLLMI, 1989 ;RUF-FELL & OWEN, 1995 ;BARABOSHKIN, 1999 ;KENNE-DY et al, 2000 ;MUTTERLOSE et al, 2003 ;RAISOSSADAT, 2006 ;JOLY & DELAMETTE, 2008 ;MATRION, 2010).
