Disphaerogena carposphaeropsis
Disphaerogena carposphaeropsis O.Wetzel, 1933; emend. Sarjeant, 1985
Tax. sr. synonym of Cyclapophysis monmouthensis Benson, 1976, according to Sarjeant, 1985.
Holotype: O.Wetzel, 1933, pl.4, fig.34; Sarjeant, 1985, pl.3, figs.1,4; Fensome et al., 1993
Locus typicus: S Baltic region
Stratum typicum: Late Cretaceous
Translation O.Wetzel, 1933: Fensome et al., 1993
Original diagnosis: O.Wetzel, 1933, p.51
Spherical, somewhat perforated shell with several large processes which in part branch and, by means of rod- or wing-like elements, are distally connected in an irregular fashion. One of the two observed specimens under consideration is strongly damaged, but the other shows distinctly that an outer lattice-like shell or skin surrounds the organism or might also exist only as a fairly irregular trabeculate- or wing-complex with few large meshes. Brown coloured.
Emended diagnosis: Sarjeant, 1985, p.142
Chorate, skolochorate cysts of spheroidal to suboval ambitus. Apical horn always longer than antapical, but by a variable ratio (1.2:1 to 3:1). Both horns surrounded by a palisade of moderately long, fibrous processes. Precingular and postcingular processes longer, fused or linked by trabeculae distally to form an equatorial tunnel, indistinctly interrupted by the sulcus. Phragma two-layered, the inner layer considerably thicker than the outer; surface of phragma microreticulate, the process bases corresponding to nodes. Archaeopyle single-plate precingular, type P, formed by loss of paraplate 3".
Size: Overall diameter 140 Ám, diameter of central body 65 Ám, length of processes about 38 Ám.
