Cyclonephelium exuberans
Cyclonephelium exuberans Deflandre and Cookson, 1955
Now Glaphyrocysta. Originally Cyclonephelium, subsequently (and now) Glaphyrocysta.
Holotype: Pastiels, 1948, pl.5, fig.11, 13 (as Membranilarnax pterospermopsis O.Wetzel, 1933, lost, according to Sarjeant, 1986)
Neotype: Eaton, 1976, pl.8, fig.2 (designated by Sarjeant, 1986)
Locus typicus (holotype): Blorquiau quarry of the SociÚtÚ Anonyme des CarriÞres de Quenast, Belgium.
Stratum typicum: Holotype: Early Eocene (Early Ypresian)
Age: Late Cretaceous
Diagnosis: Eaton, 1976, p. 255
Cyst body dorsoventrally flattened with a smooth or finely granular surface. The circular or subcircular outline may be modified by the development of one or two antapical proturbances. Processes restricted to the peripheral zone of the cyst body; variable in breadth and simple or branched, distally complexly united by traberculae and areas of variably fenestrate membrane. No processes developed on reflected precingular plates 3"" and 6"". Archaeopyle apical, tetratabular.
