Prolixosphaeridium perforospineum
Prolixosphaeridium perforospineum Dodekova 1994
Holotype Dodekova 1994: pl. V, figs. 16-18
Locus typicus: borehole R-3 Junak, depth 1695.5 m, Northeastern Bulgaria.
Stratum typicum: Tica Fm., Middle Tithonian,
Dimensions (in µm) Holotype: length of the body (without apex) breadth: 29, length of processes: 16. Range length: 43-50, breadth 26-30 length of processes: 16.
Description. Dodekova 1994, p. 27
Chorate cyst with ellipsoidal body and moderate in number of processes. The processes are long, have relatively broad bases, after that narrowed gradually and taper distally in closed conical tips, rarely blunt. The processes have perforations with variable size at its full length but they may be seen with great microscopical magnification. The surface of the autophragm is scabrate. Archeopyle apical, type tA. Operculum free. All observed specimens possess an archeopyle.
Remarks. Dodekova 1994, p. 27: The presence of long, broad and perforate processes distinguishes P. perofrospineum from all previously described species.
Occurrence. Boreholes: R-1 Junak (depth 1495 m, Tica Fm., Late Tithonian, Crassicollaria Zone); R-3 Junak (depth 1695.5 m, Tica Fm., Middle Tithonian), outcrop Mahala Popska, Sevlievo, Zlatarica-Cerni osam Fm., Late Tithonian, Paraulacosphinctes transitorius Zone.
