Spiniferites chebca
From Fensome et al., 2019:
Spiniferites chebca (Below, 1982c, p.35, pl.8, figs.7,8a–c,9) Lentin and Williams, 1993, p.604. Holotype: Below, 1982c, pl.8, figs.8a–c. Originally Spiniferites multibrevis subsp. chebca, subsequently (and now) Spiniferites chebca. NIA. Age: Hauterivian–Aptian.
---------------------------------------------------------------------------------------------------
Original description (Below, 1982c)
Diagnosis: A subspecies of Spiniferites multibrevis (Davey & Williams 1966) stat. nov. with evenly perforated endophragm and smooth to perforated periphragm, which also partially carries some granules. Broad-based, gonal processes and bi- or trifurcate, parasutureal processes bifurcate. Variants bear only a few parasutural processes and thus lead to Spiniferites ancoriferus ssp. ghiran. All processes are bifurcat or bifid again in second order. They reach about 1/4 of the equatorial diameter in length. The parasutural membranes between the processes are low. Archaeopyle praecingular, type P3".
Measurements: holotype: length of central body 54 µm, width of central body 49 µm, length of appendages 6-8 µm
other specimens: length of central body 48-56 µm, width of central body 45-50 µm, length of appendages 6-10 µm.
