Ceratocystidiopsis simplex
Ceratocystidiopsis simplex, Deflandre, 1937
Holotype: Deflandre, 1937, pl.17 [al. pl.14], fig.1.
Age: Late Cretaceous
----------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Deflandre, 1937b, p. 89] (translated from French):
Ceratidiopsis simplex n. sp.
Pl. XVII, fig. 1.
The shell itself is ellipsoidal, slightly ovoid. The hyaline membrane, very thin, envelops it entirely, but it is only clearly visible at the two poles where it forms two large pleated cones, one of which is clearly wider than the other. The integument of the shell is coarsely granular. Originally, it was shiny black due to the presence of gaseous inclusions, which escaped following very careful wear of the surface of the flint flake containing C. simplex. Later, the organism was entirely stained with ruthenium red. The membrane is pink and the shell a fairly dark red.
The dimensions are as follows: shell, approximately 58/44 μ; total length, approximately 110 μ. Only one specimen known so far, from a flint pebble collected in Paris.
