Scriniodinium oxfordianum
From Fensome et al., 2019:
Scriniodinium ?oxfordianum Sarjeant, 1962a, p.485, pl.69, figs.13–14. Holotype: Sarjeant, 1962a, pl.69, fig.14. Originally Scriniodinium, subsequently Endoscrinium, thirdly Sirmiodinium, fourthly (and now) Scriniodinium?. Questionable assignment: Riding and Fensome (2002, p.18), who questionably retained this species in Scriniodinium. Riding and Fensome (2002, p.18) considered this species to be a possible junior synonym of Scriniodinium crystallinum. Age: Oxfordian.
---------------------------------------------------------------------------------------------------
Original diagnosis: Sarjeant, 1962, p.485
A species of Scriniodinium, having a cyst of broad ly ellipsoidal shape, one face of whose hypothecal portion is somewhat flattened. Theca ellipsoidal, having a distinct tabulation, apparently 4', 6", 5''', 0p, 0''''; the sutures of ventral surface are unornamented, but sutures elsewhere bear raised crests formed by short spines, quite widely separated, whose tips are linked by a trabecula following the course of the suture.
Dimensions: Holotype: Theca length 100 µm, breadth 82 µm, cyst length 82 µm, breadth 62 µm.
