Surculosphaeridium scissospinum
Surculosphaeridium scissospinum (Yun Hyesu, 1981, p.32–33, pl.16, figs.3,7–8,10; text-figs.8a–b) Fauconnier and Pourtoy in Fauconnier and Masure, 2004, p.518.
Originally Hystrichosphaeridium, subsequently (and now) Surculosphaeridium.
Holotype: Yun Hyesu, 1981, pl.16, fig.10; text-figs.8a–b; Fensome et al., 1991, figs.3–5 — p.731; Fauconnier and Masure, 2004, pl.74, figs.4–6.
Paratype: Yun, 1981, pl.16, fig.7
Locus typicus: Timmermann brickyard near Esbeck, Germany
Stratum typicum: Early Santonian
Translation Yun, 1981: Fensome, 1991, p. 732
Original diagnosis: Yun, 1981, p. 33
This proximochorate species is characterized by short, funnel-shaped, distally irregularly ragged processes. They are always shorter than the central body radius and are narrowest at midlength. This species has the following paratabulation: 4", 6"", 0-1a, 6-7c, 6""", 2p, 1"""". The length of the processes is more or less uniform on a single specimen, but intraspecifically it varies between 1/5 and 1/2 the central body diameter.
