Corradinisphaeridium horridum
From Fensome et al., 2019:
Corradinisphaeridium horridum (Deflandre, 1937b, p.74, pl.15 [also labelled pl.12], figs.7–8) Masure, 1986, p.112. Emendation: Masure, 1986, p.112–113, as Corradinisphaeridium horridum. Holotype: Deflandre, 1937b, pl.15 (also labelled pl.12), figs.7–8; Masure, 1986, pl.1, figs.4–6 and text-fig.2. Originally Hystrichosphaeridium, subsequently
Baltisphaeridium (Appendix A), thirdly (and now) Corradinisphaeridium. Taxonomic junior synonym:
Lanternosphaeridium (as Fibrocysta?) mutinense, according to Masure (1986, p.112). Age: Senonian.
---------------------------------------------------------------------------------------------------
Original description: [Deflandre, 1937b] (translated from French):
HYSTRICHOSPHÆRIDIUM HORRIDUM n. sp.
PI. XV, fig. 7, 8.
Holotype: AJ 11, flint S. 8, pebble, Paris.
The only known specimen of this new species is very distinctive, both by the structure of the body of the chamber and by its appendages.
The globose shell is divided into fields or plates separated by lighter-colored grooves meeting at obtuse angles. It appears, from the opening of these angles, that the plates thus delimited are hexagonal. It is from the center of these plates that the powerful processes spring. Some are simple, strong, sharp horns, others are broad, forked, and stiff; still others curve, widening at their distal extremity, which is divided into several sharp spines. The overall impression is one of great robustness. The shell's integument is brownish and granular. The dimensions of the individual, the unique holotype, represented here are: shell alone, 55-57 μ; with appendages, 130-136 μ. H. horridum comes from the flint pebble S. 8 (Paris), already cited many times.
