Archaeodictyomitridae Pessagno, 1976: 49; 1977a: 41 ( sensu emend.); 1977b: 934.

Archaeodictyomitracea [sic] – Grill & Kozur 1986: 254 (= Archaeodictyomitroidea) [as a superfamily]. — O’Dogherty 1994: 69. — De Wever et al. 2001: 262.

DIAGNOSIS. — A multisegmented Nassellaria with a simple cephalis with MB, A-, V-, D- and double L-rods. The shell is covered with continuously aligned longitudinal costae. One to two (or more) rows of pores; similar rows of relict pores, or platy longitudinal depression, are arranged between adjacent longitudinal costae.

REMARKS

This superfamily consists of the Mesozoic Bagotidae Pessagno & Whalen 1982, Archaeodictyomitridae Pessagno 1976, Hsuidae Pessagno & Whalen 1982, and Unumidae Kozur 1984 (De Wever et al. 2001: 262-266). The Archaeodictyomitridae are the only known family in the Cenozoic. This type of multisegmented structure is shared with the Ruesticyrtiidae Kozur & Mostler 1979, Amphipyndacoidea and Eucyrtidioidea . Dissimilarly to the Archaeodictyomitroidea, the Ruesticyrtiidae have a more complex initial spicular system (De Wever et al. 2001: fig. 171).
