Hystrichosphaera cornuta
Hystrichosphaera cornuta Gerlach, 1961, p.180, pl.27, figs.10–12. Emendation: Stover and Hardenbol, 1994, p.38–39, as Spiniferella cornuta.
Now Spiniferites. Originally Hystrichosphaera, subsequently (and now) Spiniferites.
Holotype: Gerlach, 1961, pl.27, figs.10-12
Age: Middle Oligocene-Middle Miocene
Supplemental description: Davey and Williams, 1966, p. 43
The specimens are identical to those described by Gerlach (1961) and possess the following reflected tabulation - 3-4", 6", 6c, 5""", 1p, 1"""", with plate 6" triangular in outline. Whilst some species reflect only 3 apical plates, others show an elongate division of plate I" to give rise to two plates which are in line with the sulcus. There is occasionally an apical bulge which interrupts the otherwise regular outline of the central body and lies immediately below the apical process. Gonal and sutural processes are present, and may occasionally be open. In some individuals the large apical process possesses small lateral spines.
