Evansia wigginsii
From Fensome et al., 2019:
Evansia wigginsii (Smelror, 1988a, p.296,298, pl.8, figs.1–2; text-fig.12) Below, 1990, p.73. Holotype: Smelror, 1988a, pl.8, fig.2. Originally Pareodinia, subsequently (and now) Evansia. Age: early Oxfordian.
---------------------------------------------------------------------------------------------------
Original description (Smelror, 1988)
Description: Dinoflagellate cyst ellipsoidal to ovoidal, drop-shaped in outline. The cyst exhibits a distinct short apical horn and a broadly rounded antapex. The cyst wall is single layered and possesses characteristic coarse verrucate ornament, which appears densely spaced on the autophragm. The archaeopyle is three-paraplate intercalary (type 3I). Some specimens with the operculure attached have been observed. Reflected tabulation other than the archaeopyle
outline and the opercular paraplates is not noted. Evidence of a paracingulum or parasulcus has not been observed in any of the specimens examined.
Dimensions: Length (including apical horn) 43-47 µm, with 25-34 µm (5 specimens measured. Holotype: Length 45 µm, width 31 µm.
Etymology: Named in honor of Virgil D. Wiggins.
Holotype: S-14/51-0: B45/3, Plate VIII, 2.
Paratype: S-14/51-3: L53/0, Plate VIII, 1.
Type stratum and locality: Kong Karls Land,
