Thalassiphora flammea
From Fensome et al., 2019:
Thalassiphora flammea Cookson and Eisenack, 1967b, p.252–253, pl.42, figs.1–5.
Holotype: Cookson and Eisenack, 1967b, pl.42, fig.1.
Originally (and now) Thalassiphora, subsequently Disphaeria. Lentin and Williams (1985, p.353) retained this species in Thalassiphora.
Locus typicus: Victoria, W. Australia
Stratum typicum: Late Paleocene
---------------------------------------------------------------------------------------------------
Original diagnosis: Cookson and Eisenack, 1967, p.252
Shell approximately oval, rather thick-walled with a sub-apical archeopyle and a finely reticulate to more or less open lace-like wing.
Dimensions: Holotype: shell c. 82 µm long, c. 72 µm broad, archeopyle c. 30 x 24 µm; wing c. 50 µm wide.
Affinities:
Cookson and Eisenack, 1967, p.252: T. flammea agrees in general features with T. velata (Deflandre and Cookson, 1955) from two Western Australian Lower Tertiary deposits. However, in T. velata the winglike expansions are so faintly patterned as to give a general impression of smoothness and entirity, in contrast to the more coarsely dotted to finely open lacey appearance characteristic of T. flammea. T. flammea differs from the type species T. pelagica (Eisenack, 1954) from European Eocene deposits, in the absence of an antapical projection and type of wing structure.
