Disphaeria flammea
Disphaeria flammea (Cookson and Eisenack, 1967) Yun, 1981
Now Thalassiphora. Originally (and now) Thalassiphora, subsequently Disphaeria.
Lentin and Williams, 1985, retained the species in Thalassiphora Eisenack and Gocht, 1960.
Holotype: Cookson and Eisenack, 1967, pl.42, fig.1
Locus typicus: Victoria, W. Australia
Stratum typicum: Late Paleocene
Original diagnosis: Cookson and Eisenack, 1967, p.252: Thalassiphora flammea
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 Ám long, c. 72 Ám broad, archeopyle c. 30x24 Ám; wing c. 50 Ám wide.
Affinities:
Cookson and Eisenack, 1967, p.252: Thalassiphora flammea
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.
