Mendicodinium kemperi
From Fensome et al., 2019:
Mendicodinium kemperi Heilmann-Clausen in Heilmann-Clausen and Thomsen, 1995, p.302–303, pl.5, figs.11–12,14–16. Holotype: Heilmann-Clausen and Thomsen, 1995, pl.5, figs.11–12. Age: early Barremian.
---------------------------------------------------------------------------------------------------
Type locality: Ahlum l
Type stratum: Core depth 236 m. Lower Barremian.
Paratype 1: Heilmann-Clausen and Thomsen 1995: Pl. 5, fig. 14 (Sarstedt)
Paratype 2: Heilmann-Clausen and Thomsen 1995: Pl. 5, fig. 16 (Sarstedt)
Diagnosis: Heilmann-Clausen and Thomsen 1995, p. 302-303
Proximate cyst of subsphaerical shape, slightly flattened at apex and antapex. The autophragm is thin-walled and ornamented by fine discontinuous ridges, rugulae and granules. The sculpture partially marks parasutures. Similar sculpture elements are locally present as incomplete accessory parasutures and also occur in a non-tabular vermiculate pattern. The archaeopyle is epicystal with a hinge at the parasulcus.
Dimensions of holotype: Breadth 62 µm.
Dimensions of measured specimens: Breadth: 60 (67) 78 µm. (5 specimens measured)
Comparison: Mendicodinium caperatum BRIDEAUX, 1977 is the morphologically closest relative of M. kemperi. M. caperatum differs by having an exclusively non-tabular ornament which is of lesser relief.
