Cassiculosphaeridia reticulata
From Fensome et al., 2019:
Cassiculosphaeridia reticulata Davey, 1969a, p.142, pl.3, fig.7; pl.4, fig.3. Holotype: Davey, 1969a, pl.4, fig.3. Originally (and now)
Cassiculosphaeridia, subsequently Valensiella. Slimani (1994, p.98) retained this species in Cassiculosphaeridia.
Age: Cenomanian.
---------------------------------------------------------------------------------------------------
Original description: Davey, 1969, p.142
Diagnosis:
Shell spherical to subspherical. Shell surface bearing low ridges, forming a coarse reticulation, from which arise fine membranous crests. Shell wall lightly to densely granular.
Description:
The areas delimited by the low ridges are typically subpolygonal but may be of irregular shape. They vary considerably in size, from 2 to 10 µm in diameter. The membranous crests are very fine and tend to be flexous since supporting structures are absent.
