Hystrichosphaera ramosa var. granosa
Hystrichosphaera ramosa ssp. granosa Davey and Williams 1966
Now Spiniferites ramosus ssp. granosus. Originally Hystrichosphaera ramosa var. granosa, subsequently Spiniferites ramosus var. granosus, thirdly (and now) Spiniferites ramosus ssp. granosus.
Holotype: Davey and Williams, 1966, pl.4, fig.9; Bujak et al., 1980, pl.4, figs.4-5
Locus typicus: London Clay, Sheppey, Kent, England
Stratum typicum: Early Eocene
Original diagnosis: Davey and Williams, 1966, p. 35
A variety of H. ramosa (Ehrenberg) similar to H. ramosa var. gracilis except that the surface of the central body is coarsely granular. Height of granules ranging up to 0.5 µm.
Dimensions: holotype: diameter of central body 35 by 42 µm, length of processes up to 19 µm. Range: diameter of central body 33-45 µm, length of processes up to 19 µm.
