Kenleyia nuda
From Fensome et al., 2019:
Kenleyia nuda de Coninck, 1969, p.45–46, pl.13, figs.24–25. Holotype: de Coninck, 1969, pl.13, figs.24–25. Originally Kenleyia?, subsequently (and now) Kenleyia. Questionable assignment: de Coninck (1969, p.45) — however, Brinkhuis and Leereveld (1988, p.17) included the species in Kenleyia without question. Age: Early Eocene.
---------------------------------------------------------------------------------------------------
The single specimen on which the species is based is most probably reworked from the Danian (HB-LPP).
Original description (de Coninck, 1969):
Kenleyia ? nuda nov. sp. (PI. XIII, figs. 21 and 25.)
Holotype. — Kallo -37 8 m. Preparation 2; coord. 53.6-104.1.
Diagnosis. — The globose to subangular organism has a vague, slightly helical girdle and two short, pointed, polar, opposite processes. A few vague lines on the bare surface indicate an unclear tabulation. The angles, clearly visible on the outline, indicate the levels where the apical plates touch the precingulate plates and where the postcingulate plates meet those of the antapical region. I am not sure of the presence of an archaeopyle. The organism's characteristics nevertheless allow us to relate it to the genus Kenleyia, well represented in the upper levels of the Landenian of Kallo.
Body dimensions: 68 µm.
Process dimensions: approximately 8 µm by 10 µm at the base.
Total wingspan: 82 µm by 68 µm.
