Cleistosphaeridium polyozum
From Fensome et al., 2019:
Cleistosphaeridium polyozon (Brosius, 1963, p.45, pl.1, fig.6; pl.6, fig.5; text-figs.2a–d) Stover and Evitt, 1978, p.31–32. Holotype: Brosius, 1963, pl.1, fig.6. NOW Impletosphaeridium?. Originally Baltisphaeridium (Appendix A), subsequently
Cleistosphaeridium?, thirdly Surculosphaeridium, fourthly (and now) Impletosphaeridium. Questionable
assignment: Stover and Evitt (1978, p.31). For etymology, see under Impletosphaeridium? polyozum. Age: Late
Oligocene.

Original description, Brosius, 1963 [translation PKB 2024]: Baltisphaeridium polyozon n. sp. (Plate 1, Figure 6; Plate 6, Figure 5, Figure 2 (2 a-d))
Diagnosis: Strong, fleshy, massive appendages with a widened base sit irregularly on a smooth, delicate capsule. They usually fork sim in half. The branches usually split into 2 (but also 3-5) parts, the ends of which (can only be observed under the highest magnification) can be slit into 3-7 small pins. There are usually more than 20 processes. Basal adhesions are not uncommon. Round to oval loopholes occur. The specimen shown by SCHERER under Figure 1 probably belongs to this species. However, it appears to be more oval than most of our shapes.
Derivatio nominis: πολύοζοϛ = full of branches.
Locus typicus: Firnsbach borehole (58-63.50 m).
Stratum typicum: Kassel sea sand (Upper Oligocene).
Holotype: Ri 23/36 (Plate 1 Image 6).
Paratypoid: Ri 23/37 (Plate 6, Figure 5).
Dimensions of the holotype: diameter of the capsule: 40 μ, length of the processes: 20 μ. Average capsule diameter: 33-36 μ. Length of the processes: 18-24 μ. Number of specimens examined: 25.
Occurrence: Glimmerode, Stolzenbach (15-18.3 m), Oberkaufungen 5/6 (42.8-44 m), Firnsbach (53-58 m).
