Family SUTTONIIDAE Schaaf, 1976

sensu Dumitrica (2019)

Suttonidae [sic] Schaaf, 1976: 790 (= Suttoniidae ) [in Nassellaria View in CoL ]. — Dumitrica 1983b: 41 ( sensu emend. ) [in Spumellaria View in CoL ].

Suttoniidae – De Wever et al. 2001: 125-126 [in Spumellaria View in CoL ]. — Afanasieva et al. 2005: S284 [in Order Lobatiradiata ]. — Afanasieva & Amon 2006: 126. — Dumitrica 2019: 40-41 ( sensu emend. )

TYPE GENUS. — Suttonium Schaaf, 1976: 790 [type species by monotypy: Suttonium praedicator Schaaf, 1976: 790 ].

INCLUDED GENERA (Cenozoic only). — Homunculodiscus Dumitrica, 2019: 41. — Parasuttonium Dumitrica, 2019: 47. — Suttonium Schaaf, 1976: 790 .

DIAGNOSIS. — Bilaterally symmetrical spumellarians with initial skeleton consisting of an eccentric microsphere with or without primary rays and a crescent shaped deuteroconcha. Skeleton thin made usually of two parallel lattice plates interconnected by short bars. Rays, when present, surrounded by a cortical shell forming three arms in the most evolved members ( Dumitrica 2019: 40).

STRATIGRAPHIC OCCURRENCE. — Early Paleocene-Holocene.

REMARKS

The internal skeletal structure of Homunculodiscus was already documented ( Dumitrica 2019: figs 1.a-1.g, 2.a-2.h, 3a.-3.d, 4.a-4.d), Parasuttonium ( Dumitrica 2019: figs 6.a, 6.b) and Suttonium ( Dumitrica 2019: figs 6.c, 6.d). The taxonomic position of the Suttoniidae has been changed among Nassellaria , Spumellaria and Lobatiradiata . The history and the definition of the current taxonomic position was documented in Dumitrica (2019).
