2.6.3 | Rostellariidae + Seraphsidae

Hypotheses on the earliest rostellariid range from the Cenomanian–Turonian to the Maastrichtian ( Bandel, 2007; Roy, 1996). The oldest specimen according to Tracey et al. (1993) is? Dientomochilus stueri from the Coniacian (Condat, France: Cossmann, 1904, pl. 9, figs 5 and 6); however, this is an incomplete internal mould. Eucalyptraphorus palliatus (Forbes, 1846) is reported from the Turonian-Coniacian and Maastrichtian- Campanian (Trichinopoly and Ariyalur Groups, India: Stoliczka, 1868, pl. 2, figs 18–20; Acharyya & Lahiri, 1991); the former is a mould, and the latter an incomplete shell. A Calyptraphorus itamaracensis specimen (Gramame Formation, Pernambuco, Brazil: Muñiz, 1993, pl. 11, figs 5, 8), reported from the Campanian, was considered the oldest representative by Perrilliat and Vega (1997); however, this formation has since been identified as Maastrichtian (e.g. El Gadi and Brookfield, 1999). Therefore, we use E. palliatus (Campanian/Maastrichtian) to date the crown age of Rostellariidae + Seraphsidae (Table 1).
