Phylloceras (Hypophylloceras)

Cephalopoda - Phylloceratida - Phylloceratidae

Taxonomy
Phylloceras (Hypophylloceras) was named by Salfeld (1924) [Sepkoski age: K (Vala) - K (Maes-u)]. Its type is Phylloceras onoensis.

It was reranked as Hypophylloceras by Packard (1960), Young (1979), Morozumi (1985), Avram and Gradinaru (1993), Wright et al. (1996), Courville and Odin (2001), Főzy (2001), Sepkoski (2002), Murphy and Rodda (2006), Ifrim et al. (2013).

It was assigned to Phyllocerinae by Young (1979); to Phylloceratidae by Morozumi (1985), Avram and Gradinaru (1993); to Phylloceratitida by Sepkoski (2002); to Calliphylloceratinae by Murphy and Rodda (2006); to Phylloceratinae by Packard (1960), Wright et al. (1996), Courville and Odin (2001), Főzy (2001), Ifrim et al. (2013); and to Phylloceras by Förster (1975), Kennedy and Klinger (1977), Cooper and Kennedy (1979), Wiedmann (1979), Renz (1982), Förster and Weier (1983), Wright and Kennedy (1984), Klinger (1985), Khiami and Murphy (1988), Kennedy (1994), Kennedy (1995), Reboulet (1996), Szives (2007), Kennedy and Morris (2018), El Qot (2018), Kennedy et al.
