Spiniferites pseudofurcatus ssp. verrucosus
Spiniferites pseudofurcatus subsp. verrucosus Schiøler, 2005, p.31, pl.19, figs. 1–4.
Holotype: Schiøler, 2005, pl. 19, fig.2.
Age: latest Lutetian–Bartonian.
Original description (Schioler, 2005):
Spiniferites pseudofurcatus verrucosus ssp. nov. (Pl. 19, figs 1–4)
Derivation of name. Latin: verrucosus, -a, -um, warty. With reference to the characteristic ornamentation on the endophragm.
Diagnosis. Skolochorate, spiniferate, gonyaulacoid cyst of intermediate to large size. The processes terminate bifurcate to tetrafurcate or ramify. Low septal crests connect the processes proximally. The periphragm is smooth, the endophragm is coarsely verrucate to vermiculate.
Holotype. MGUH 26757, SM 501 (Pl. 19, fig. 2).
Paratypes. (1) MGUH 26758 (Pl. 19, fig. 1); (2) MGUH 26759 (Pl. 19, fig. 3).
Horizon. Horda Formation, 6080–6110# (1853.2–1862.3 m). Upper Bartonian.
Stratigraphical range. Uppermost Lutetian to Bartonian in Alma-1X (zones E6c–E7b of Mudge & Bujak, 1996).
Remarks. The new subspecies differs from the autotype Spiniferites pseudofurcatus pseudofurcatus and the two other subspecies S. pseudofurcatus obliquus (Wall, 1967) Lentin & Williams, 1973 and S. pseudofurcatus granulatus Schiøler, 1994 in having a coarsely verrucate to vermiculate surface ornament instead of being smooth-walled or granulate.
