Gonyaulax granuligera
Gonyaulax granuligera Klement, 1960; Emendation: Sarjeant, 1984a, p.156, as Cryptarchaeodinium granuligerum.
NOW Cribroperidinium. Originally Gonyaulax, subsequently Gonyaulacysta, thirdly (and now) Cribroperidinium, fourthly Rhynchodiniopsis, fifthly Cryptarchaeodinium, sixthly Acanthaulax.
Taxonomic senior synonym: Gonyaulax (as Gonyaulacysta, now Cribroperidinium) granulata, according to Fisher and Riley (1980, p.321) - however, Sarjeant (1984a, p.156) retained Gonyaulax (as Cryptarchaeodinium) granuligera.
Holotype: Klement, 1960, pl.5, figs.4-5; Sarjeant, 1984, pl.1, figs.3-4, text-fig.1; Jan du Chene et al., 1986, pl.27, figs.11-14
Paratypes: Klement, 1960
Locus typicus: Bore Scherstetten 1, SW Germany
Stratum typicum: Middle Oxfordian-Early Kimmeridgian
Translation Klement, 1960: LPP
Original diagnosis: Klement, 1960, p.41
A species of the genus Gonyaulax with following tabulation: 4", 6"", 6""", 1p, 1ppl, 1"""". Elongated polyedrical theca ending in a prominent, long, apical horn. Plates and sutures granulate to tuberculate. Plates often with parallel, granulate suture duplications. Spiral girdle furrow, displaced in c.1ยข to 2 of its width. Longitudinal furrow from 1. apical plate to antapex, widened on hypotheca with additional lower plate.
Original description: Klement, 1960, p.41-42
This rare species differs from G. granulata in the elongated polyedrical habitus with prominent apical horn. Tabulation, suture pattern and ornamentation of plates are similar to G. granulata.
Theca of slightly polygonal, elongated outline with conical epitheca, ending in the apical horn. Apical horn relatively long, hollow in the lower third, solid in the upper part. Distal end trifurcate, on holotype with one additional thorn on half its length.
