Oligosphaeridium levimarginatum
From Fensome et al., 2019:
Oligosphaeridium levimarginatum Marheinecke, 1992, p.64–65, pl.12, figs.4,10–11. Holotype: Marheinecke, 1992, pl.12, fig.4; Fauconnier and Masure, 2004, pl.57, fig.10. Contrary to the opinion of Lentin and Williams (1993, p.461), Williams et al. (1998, p.436) considered this name to be validly published. Age: late early–early late Maastrichtian.
---------------------------------------------------------------------------------------------------
Locus typicus: Hemmoor, Lower Saxony, Germany
Stratum typicum: Early Maastrichtian
Translation Marheinecke, 1992: LPP
Original description: Marheinecke, 1992, p. 64
Cyst habit sphaeroidal to subsphaeroidal, wall composed of pedium and luxuria which forms 16-18 tubifom processes. Processes intraareate, distal ends open with smooth margins. Length of processes ca. 2/3 of the central body diameter. Surface of central body smooth. Cingular- and sulcal processes missing. Areation reflected by distribution of processes. Accedation formula ?PR, 4', 6'', NRc, 5-6''', 1p, 1''''. Archaeopyle: apical 1'+2'+3'+4'; operculum secate, foederate (?PR+1'+2'+3'+4')s.
Affinities:
Marheinecke, 1992, p. 64: O. levimarginatum differs from O. complex in the decelopment of the distal process margins. Processes compared to central body shorter. Overall size smaller than O. complex.
