Lingulodinium pugiatum
Lingulodinium pugiatum (Drugg, 1970) Wall and Dale in Wall et al., 1973
Originally Operculodinium, subsequently (and now) Lingulodinium.
Holotype: Drugg, 1970, fig.16E
Locus typicus: Hinds County, Mississippi, USA
Stratum typicum: Oligocene
Original description: Drugg, 1970, p. 819: Operculodinium pugiatum
Spherical tract, precingular archeopyle, wall thin and finely granulate. Numerous processes, dagger-shaped in outline, closed proximally and distally. The process walls are thin and smooth. The length of the processes is about 12 to 15 µm although a few short ones are sometimes interspersed with the normal ones on the ventral side. The tract diameter ranges from 48 to 68 µm.
Affinities:
Drugg, 1970, p. 819: Operculodinium pugiatum
Operculodinium pugiatum most closely resembles Lingulodinium machaerophorum (Deflandre and Cookson) Wall, 1967, but differs in the mode of archeopyle formation.
