Surculosphaeridium basifurcatum
Surculosphiaeridium? basifurcatum Yun, 1981
Questionable assignment: Yun Hyesu (1981, p.39) and Fauconnier and Pourtoy in Fauconnier and Masure (2004, p.519) as a problematic species.
Holotype: Yun, 1981, pl.16, fig.13, text-figs.l0a-b; Fensome et al., 1991, figs.1,3-4 - p.585
Paratype: Yun, 1981
Locus typicus: Timmermann brickyard near Esbeck, Germany
Stratum typicum: Early Santonian
Translation Yun, 1981: Femsome et al., 1991, p. 586
Original diagnosis: Yun, 1981, p. 39
Each plate of the chorate cyst has a group of 2-4 short, solid spines or one thick spine, which is basally forked into 3-4 small finger-like branches. These branches are sometimes simply or variously ramified. Their ends are acuminate or truncated. The length of the processes does not exceed the central body radius. The species shows an apical archeopyle. The arrangement of the spines is: 4", 1a, 6-7", 6-7c, 6""", lp,
Original description: Yun, 1981, p. 39
The central body consists of a smooth and finely perforated endophragm. The individual elements of a spine group or isolated spines taper distally and have rounded or acuminate tips.
