Rectotormentum Nazarov & Ormiston, 1985: 41 .

TYPE SPECIES. — Rectotormentum fornicatum Nazarov & Ormiston, 1985 ( Nazarov & Ormiston 1985: 41, pl. 5, fig. 10-11; holotype never figured, paratype pl. 5, fig. 11).

AGE AND LOCATION OF TYPE MATERIAL. — Artinskian (Lower Permian), Don village, Ural River, Southern Urals, Russia.

TAXON CODE. — 213.

STATUS. — Valid.

DIAGNOSIS. — “ Tormentidae with a spongy outer layer and varied structure of the internal framework. Among them are developed several intercalated shells whose outlines duplicate the external outline. The shells are connected to one another by irregularly positioned beams and three, rarely more, rays arising from the internal framework. The structure of the internal framework is not adequately known. In one species it is represented by a non-porous sphere with rays emanating at angles of 120”; among others, it gives the impression of the presence of a three-rayed spicule. Terminal spines developed in some species, but they also may be absent” ( Nazarov & Ormiston 1985: 41).
