Achilleodinium spp.

 

Achomosphaera alcicornu

 

Adnatosphaeridium multispinosum

 

Aiora fenestrata

 

Aireiana verrucosa

 

Algidasphaeridium minutum var. cezare

 

Algidasphaeridium minutum var. minutum

 

Alisocysta circumtabulata

 

Alisocysta margarita

 

Alisocysta reticulata group

Remarks: In this group, morphologically closely related forms assignable to Alisocysta reticulata, Cassidium spp., and Eisenackia crassitabulata are combined (cf. Crouch, 2001).

 

Alterbidinium acutulum

 

Alterbidinium distinctum

 

Alterbidinium spp. (pars)

Remarks: This group is combined with the morphologically closely related Diconodinium spp. in the case of Hole 1172D analyses. The latter differ from Alterbidinium spp. in being essentially acavate.

 

Apectodinium homomorphum

 

Arachnodinium antarcticum

 

Areoligera? semicirculata

 

Ataxiodinium choane

 

Batiacasphaera spp.

Remarks: This group constitutes several new species, to be formally described elsewhere.

 

Bitectatodinium tepekiense

 

Brigantedinium? sp.

Remarks: This species is throughout comparable to species of Brigantedinium, but differs by having a distinct periphragm, in ideally preserved cases displaying a long, slender apical horn, besides two long and slender antapical horns. The length of the horns may be as much as four times the diameter of the central body. This outer wall is delicate and thin, and is often either removed though oxidation or mechanical disturbance or may be present as a wrinkled, poorly defined thin outer membrane. Since Brigantedinium species are considered acavate, the species is questionably attributed here to the genus. The species is most probably conspecific with forms depicted by Mohr (1990) as "Brigantedinium sp." from sediments with a similar age off Seymour Island (DSDP Site 696). The species will be formally described elsewhere.

 

Brigantedinium spp.

 

Cerebrocysta spp.

Remarks: This group constitutes several new species, to be formally described elsewhere.

 

Cerodinium sp. A

Remarks: This taxon has a characteristic elongate shape with outward-pointing, short antapical horns and is here separated from other forms, grouped as Cerodinium spp. It is apparently restricted to the Maastrichtian interval, and is possibly conspecific with Broomea? sp. of Askin (1988a) and/or Cerodinium sp. A of Smith (1992). The species will be formally described elsewhere.

 

Cerodinium spp. (pars.)

 

Charlesdowniea coleothrypta

 

Charlesdowniea edwardsii group

Remarks: Forms whose morphology ranges between C. edwardsii and Charlesdowniea columna are combined in this group.

 

Circulodinium compactum

 

Cleistosphaeridium spp.

 

Cordosphaeridium fibrospinosum group

 

Cordosphaeridium minimum

 

Corrudinium spp.

Remarks: This group constitutes several new species, to be formally described elsewhere.

 

Cribroperidinium sp. A.

Remarks: This taxon is morphologically comparable to Impagidinium waipawaensis of Wilson (1988), but differs by lacking perforations in the parasutural ridges. The dextral torsion warrants attribution to Cribroperidinium. The species will be formally described elsewhere.

 

Cribroperidinium spp. (pars.)

 

Dapsilidinium spp.

 

Deflandrea antarctica group

Remarks: Forms morphologically ranging between D. antarctica and Deflandrea cygniformis are combined in this group (essentially all forms with a distinct bell-shaped hypotract and short antapical horns).

 

Deflandrea convexa group

Remarks: Forms of Deflandrea characterized by a condensed periphragm are combined in this group.

 

Deflandrea phosphoritica group

Remarks: Forms of Deflandrea characterized by having a periphragm corresponding to the general periphragmal outline of D. phosphoritica are combined in this group, regardless of ornamentation of the periphragm and/or endophragm (e.g., including D. granulosa, D. granulata, D. robusta, D. spinosa, D. heterophlycta, and D. webbii)

 

Deflandrea sp. A

Remarks: This rather large species of Deflandrea may be characterized by a distinctly triangular endophragm and by having a relatively long apical and short antapical horns. It is possibly partly conspecific with Deflandrea prydzensis (manuscript name) of Truswell, 1997. The species will be formally described elsewhere.

 

Diconodinium spp.

Remarks: This group constitutes several new species, to be formally described elsewhere.

 

Dinogymnium spp.

 

Dinopterygium sp. A

Remarks: This species of Dinopterygium closely resembles Dinoptergium cladoides pending the concept used of the latter. Further study will further elucidate morphological relationships. In any event, representatives of Dinopterygium sensu stricto have never been reported from deposits as young as latest Maastrichtian in age. The species will be formally described elsewhere.

 

Dinopterygium spp. (pars.)

Remarks: Specimens assigned to Dinopterygium spp. (pars.) are relatively small representatives of the genus. Many of these are assignable to "Dinopterygium cladoides sensu Morgenroth."

 

Diphyes colligerum

 

Diphyes ficusoides

 

Distatodinium spp.

 

Dracodinium waipawaense

 

Echinidinium spp.

 

Elytrocysta spp.

 

Enneadocysta partridgei

 

Enneadocysta pectiniformis

 

Enneadocysta sp. A

Remarks: This species of Enneadocysta closely resembles Areosphaeridium diktyoplokum but differs by having two antapical processes, distally united by a single perforated platform, and by being dorso-ventrally compressed. The latter features are more typical for Enneadocysta, although clearly the form (and other species of Enneadocysta) is/are gonyaulacoid sexiform rather than partiform as suggested by Stover and Williams (1995). The species will be formally described elsewhere.

 

Eocladopyxis spp.

Remarks: This group constitutes several new species, to be formally described elsewhere.

 

Exochosphaeridium bifidum

Spiniferella cornuta

 

Spiniferites pseudofurcatus

 

Spiniferites mirabilis

 

Spiniferites cf. mirabilis

Remarks: This taxon resembles S. mirabilis but differs by having a much larger size range (up to 120 µm) and by less well defined and developed processes.

 

Spiniferites sp. A

Remarks: This species of Spiniferites is characterized by it having septate processes, distally expanding into a broad trifurcation a la Spiniferites pseudofurcatus. It is however much smaller than typical S. pseudofurcatus. The species will be formally described elsewhere.

 

Spiniferites sp. B

Remarks: This species of Spiniferites is characterized by it having (1) intergonal bifurcate processes and (2) sutural ridges that are higher at gonal junctions, giving the cyst broad arch-shaped sides. The species will be formally described elsewhere.
