Spiniferites ramosus var. ramosus
Spiniferites ramosus var. ramosus
Autonym, now redundant.
Originally Hystrichosphaera ramosa var. ramosa, subsequently Spiniferites ramosus var. ramosus.
Harker and Sarjeant in Harker et al., 1990, retained the autonym as Spiniferites ramosus var. ramosus. Lentin and Williams, 1993, followed Lentin and Williams, 1989, and retained it as Spiniferites ramosus ssp. ramosus.
Age: Late Cretaceous

G.L. Williams short notes on species, Mesozoic-Cenozoic dinocyst course, Urbino, Italy, May 17-22, 1999 - LPP VIEWER CD-ROM 99.5.
Spiniferites ramosus (Ehrenberg, 1839) Mantell, 1854, emend. Davey and Williams, 1966a. Emendation from Davey and Williams (1966a, p.32). It possesses a thin-walled central body, smooth, reticulate or granulate. Gonal with or without intergonal processes always extending beyond confines of sutural crests, solid or hollow, the latter closed distally. Typical gonal processes trifurcate, sutural processes bifurcate, both commonly terminating distally in a small bifurcation. Size: holotype, diameter of central body 42 by 48 µm, length of processes 13-25 µm.

Emended diagnosis: Davey and Williams, 1966, p. 32: Hystrichosphaera ramosa
A species of Hystrichosphaera possessing a thin walled central body, smooth, reticulate or granular. Gonal +/- sutural processes always extending beyond confines of sutural crests, solid or hollow, the latter closed distally, Typical gonal processes trifurcate, sutural processes bifurcate, both commonly terminating distally in a small bifurcation.
