Ellipsoidictyum circulatum
Ellipsoidictyum circulatum (Clarke and Verdier, 1967) Lentin and Williams, 1977
Now Elytrocysta. Originally Dictyopyxidia, subsequently Ellipsoidictyum, thirdly (and now) Elytrocysta.
Holotype: Clarke and Verdier, 1967, pl.1, fig.11
Age: Cenomanian Santonian
Original diagnosis (Dictyopyxidia circulata) Clarke and Verdier, 1967, p.68:
A species of Dictyopyxidia with an inner body and outer wall connected by a reticulum; the overall shape is circular.
Original description (Dictyopyxidia circulata) Clarke and Verdier, 1967, p.68:
Inner body and outer wall circular, connected by means of a low reticulum 1-1.5 Ám high. The muri are 1.0 µm thick and enclose irregular and polygonal shaped luminae. An elongation of the reticulum parallel to the equator suggests the presence of a girdle in many specimens. Archaeopyle is apical and indented; there are no apical or antapical horns.
Measurements: Length 39-45 µm, breadth 35-40 µm.
