Hoploscaphites
Taxonomy
Hoploscaphites was named by Nowak (1911) [Sepkoski's age data: K Camp-u K Maes-u Sepkoski's reference number: 2,971,1107].
It was reranked as Scaphites (Hoploscaphites) by Jeletzky (1952) and Birkelund (1965).
It was assigned to Scaphites by Jeletzky (1952) and Birkelund (1965); to Ammonoidea by Sepkoski (2002); to Scaphitinae by Riccardi (1983), Kennedy and Summesberger (1986), Kennedy and Summesberger (1987), Ward and Kennedy (1993), Landman and Waage (1993), Kennedy and Cobban (1993), Kennedy (1993), Kennedy and Cobban (1994), Arkadiev et al. (2000), Landman and Cobban (2003) and Landman et al. (2010); and to Scaphitidae by Machalski et al. (2012).
