Dracodinium crispum
From Fensome et al., 2019:
Dracodinium crispum (Agelopoulos, 1967, p.21–22, pl.3, fig.8; pl.4, figs.5a–b) Williams et al. 2015, p.304. Holotype: Agelopoulos, 1967, pl.3, fig.8. Originally Wetzeliella, subsequently (and now) Dracodinium. Age: Late Eocene.

Original description: [Agelopoulos, 1967] (translated from German):
Wetzeliella (W) crispa n. sp.
Pl. 3 Fig. 8, Pl. 4 Fig. 5a - 5b
Holotype: Prb. 13 No. 158 Pl. 3, Fig. 8
Paratypoid: Prb. 19 No. 229 Pl. 4, Fig. 5a - 5b
Locus typicus: Heiligenhafen (Hohes Ufer)
Stratum typicalum: Upper Eocene
Diagnosis: Inner capsule roundish-oval, rough-walled, dark reddish-brown in color, slightly pressed outward on the sides.
Carapace unclad. A very narrow space exists between the inner body and the outer edge of the carapace. Apical and lateral horns are well developed. Antapic horns are shorter than the apical horn. Transverse furrow and longitudinal furrow are not developed. A +/- rounded pyloma is always present below the apex. The shell bears bristles that are slightly forked at their ends. A lamellar margin is present along the shell edge.
Description: The inner body is thick-walled and dark reddish-brown in color, surrounded by a non-platy shell. A very narrow space remains between the outer edge of the shell and the inner capsule. The apical horn is well-developed, longer than wide. It bears hair-like bristles, and its end is extended to a point.
The lateral horns are broad and short, partially blunt, and also covered with hair-like bristles.
The anta-apical horns are smaller than the apical horn and of equal length. The capsule forms protrusions (ears) that protrude into the apical horn and the lateral horns. The specimen (Prob. 19 No. 236) shows the following image:
The capsule is very strongly compressed outward at the sides and protrudes into the lateral horns. As a result, the inner body takes on a somewhat cross-like shape. The ± rounded hatching hole is always present. It is located below the apex and is sometimes open or closed by the calotte.
The shell bears setae that are long and thin, with a faintly recognizable fork at their ends. The setae are more common at the edge of the shell than in the rest of the shell. A lamellar border is attached to the edge of the outer shell. The lamellae of this border are of varying width and length. They sometimes bear setae, and their ends form a point or two lobes. Hair-like setae often grow between them.
This Wetzeliella species is reminiscent of Wetzeliella samlandica (EISENACK 1954, p. 59), but the presence of the lamellar margin argues against its classification as the aforementioned species.
Number of specimens: 4
Dimensions of the holotype:
Length 144 μ, width 131 μ, length of the inner capsule 99 μ, width 77 μ
Paratypoid:
Length 141 μ, width 118 μ, length of the inner capsule 77 μ, width 74 μ
Another specimen: Length 106 μ, width 102 μ, length of the capsule 77 μ, width 86 μ.
Occurrence: Late Eocene
