Operculodinium centrocarpum ssp. novum
Operculodinium centrocarpum ssp. novum Marheinecke, 1992
Contrary to the opinion of Lentin and Williams (1993, p.466), Williams et al. (1998, p.441) considered this name to be validly published.
Holotype: Marheinecke, 1992, pl.10, figs.4,7-8
Locus typicus: Hemmoor, Lower Saxony, Germany
Stratum typicum: Late Maastrichtian
Translation Marheinecke, 1992: LPP
Original description: Marheinecke, 1992, p. 54
Cyst habit sphaeroidal to subsphaeroidal. Wall composed of pedium and luxuria which develops a high number of (>100) solid, capitate processes. The surface of the central budy is granulate, the distribution of processes irregular. Length of processes ca 1/4 of central body diameter. Cingulum and sulcus not indicated. Areation: indicated by archaeopyle only. Archaeopyle: precingular, 3""; operculum secate.
Affinities:
Marheinecke, 1992, p. 54: O. centrocarpum ssp. novum is similar to O. centrocarpum ssp. centrocarpum but does not show the concentration on the area-boundaries. It differs from O. centrocarpum ssp. amplum (W.Wetzel 1955) Sarjeant 1984 in the shape and number of processes.
