Spiniferites bejui
Spiniferites bejui Masure et al., 1998, p.266, pl.3, figs.3–4; text-fig.6.
Holotype: Masure et al., 1998, pl.3, figs.3–4.
Age: Coniacian?–Santonian.
Original description (Bejui et al., 1998):
Spiniferites bejuii n. sp. (Pl. 3, Figs. 3, 4; Fig. 6)
Derivation of name: In honor of Dr. Beju, palynologist.
Diagnosis: Dinoflagellate cysts skolochorate; body subspherical, bearing gonal and intergonal processes; processes connected at their bases by low parasutural bridge-like septal structures; gonal processes proximally ramified, distally trifurcate; intergonal processes proximally ramified, distally bifurcate; gonyaulacoid paratabulation indicated mainly by parasutural septa and gonal processes, archeopyle precingular, type P, free operculum.
Holotype: Slide 1: F 34, Sample 159-959D-65R-2, 27−30 cm.
Type locality: Hole 959D, offshore Côte d’Ivoire and Ghana, Côte d’Ivoire-Ghana Transform Margin.
Type biohorizon: Santonian, 1025.87 mbsf.
Housed: In the Centre Scientifique Georges Deflandre of the National Museum of Natural History in Paris, France.
Dimensions: Holotype: length of central body 48 µm, total length of processes 10 µm, height of parasutural septa, up to 4 µm. 10 specimens measured. Length of central body, 48(51)65 µm, length of processes 7(10)15 µm, length of parasutural septa 1(2.2)4 µm.
Description: Shape: skolochorate dinoflagellate cyst, with subspherical central body. Wall relationship: composed of a periphragm and an endophragm appressed. Wall features: periphragm with scabrate surface; solid gonal and intergonal processes, without membrane, proximally ramified, connected by parasutural septa formed by solid bridge-like structures; gonal process tips with trifide primary furcation and bifide secondary furcation; intergonal process tips with bifide primary and secondary bifurcations; endophragm smooth. Paratabulation: gonyaulacoid indicated by parasutural septa combined with processes: ?pr, 3−4′, 5−6′′, 6c, 5−6′′′, 1p, 1′′′′, Xs. Paracingulum: indicated by parasutural septa and processes. Parasulcus indicated by parasutural features. Archeopyle precingular, type P (3′′) with free operculum.
Comparison: S. bejuii differs from other species of the genus in having parasutural septa formed by solid bridge-like elements and gonal and intergonal processes resting on ramified bases. Occurrence: Hole 959D (see Fig. 2, number 5), from Sample 159-959D- 67R-2, 57−61 cm (1045.37 mbsf), to Sample 159-959D-65R-1, 92−95 cm (1015.62 mbsf), Coniacian? to Santonian.
