Hystrichodinium furcatum
From Fensome et al., 2019:
Hystrichodinium furcatum Alberti, 1961, p.16, pl.9, figs.7–8. Holotype: Alberti, 1961, pl.9, fig.8. Age: Hauterivian.
---------------------------------------------------------------------------------------------------
Original description: [Alberti, 1961] (translated from German):
Hystrichodinium furcatum n. sp.
Plate 9 Figs. 7 and 8
Holotype: The specimen preserved in specimen no. A12 and shown in Plate 9 Fig. 8.
Typical location: Borehole Werle 3.
Typical stratum: Epithelial ridge.
Diagnosis: Shell spherical to ovoid, epithelial and hypothelial almost equal in size, rounded at the poles. Epithelial sometimes slightly more conical than the hypothelial. Transverse furrow narrow, slightly depressed.
With numerous, slightly broadened, long, thin processes, which are (simply) forked distally.
Notes: The long, thin processes are particularly common at the poles and at the edges of the transverse furrow. The shell membrane is delicate and translucent.
Relationships: From H. ramoides n. sp. The present species differs in its distally simply forked processes and the lack of ornamentation on the shell surface.
Holotype dimensions: length 54 μ, width 51 μ, length of processes between 25 μ and 28 μ.
Material: 10 specimens.
Occurrence: upper subcutaneous tissue of the Werle 3 borehole, upper subcutaneous tissue of the Werle 5 borehole,
subcutaneous tissue of Haverlahwiese?

Hystrichodinium aff. H. furcatum of Nohr-Hansen 1993
Comments: Nohr-Hansen 1993, p. 73
The relatively few specimens recorded in the present study differ slightly in body shape from the type material described by Alberti 1961 and the processes are significantly longer than on the holotype. Also the distal furcation of the processes have shorter branches.

Hystrichodinium furcatum Alberti, 1961, has long, slender processes which branch once distally. The processes are most abundant at the poles and on the cingulum Size: holotype, length 54 µm, width 51 µm, processes between 25-28 µm.
