Deflandrea kansana
Deflandreakansanum (Tasch in Tasch et al., 1964, p.196, pl.1, fig.1) Lentin and Williams, 1973, p.42.
Holotype: Tasch et al., 1964, pl.1, fig.1.
Now Ovoidinium?. Originally Peridinium (Appendix B), subsequently Deflandrea?, thirdly (and now) Ovoidinium?, fourthly Ascodinium?. Questionable assignment: Lentin and Williams (1973, p.42).
Age: Albian.
Original description (Tasch et al, 1964)
Diagnosis: General polygonal configuration of theca; wide equatorial band separating broadly expanded hypotheca from more tapered epitheca; continuous uncurved posterior plate terminating et either end in two pointed projections (antapical horns). Plate system poorly defined.
Measurements: Length (excl. horns), 48 µm; width along girdle, 40 µm; width of girdle, 7 µm; distance between centers of antapical horns, 20 µm; length of horns, 12 µm.
Discussions: The triangular apical indentation correstonds to a missing apical plate (“apical archeopyle” of Evitt). The uncurved posterior plate bearing pointed projections or horns distinguishes the new species.
Holotype: WU-DF 0168. Slide no. 1024. Coordinates: R 21.5, D. 12.5.
Locality: Sampling interval 4-I-J.
