Valvaeodinium perpunctatum
Valvaeodinium perpunctatum (Wille and Gocht, 1979) Below, 1987
Originally Comparodinium, subsequently (and now) Valvaeodinium.
Holotype: Wille and Gocht, 1979, fig.28, nos.7a-c
Locus typicus: Gomaringen, Swabian Alb, S Germany
Stratum typicum: Early Pliensbachian
Translation Wille and Gocht, 1979: LPP
Original diagnosis: Wille and Gocht, 1979, p. 238
Outline ellipsoidal to lightly biconical, wall thin, structureless, loosely set with 0.5-1 µm high pointed cones. These are generally unarranged, but may in single specimens indicate a paratabulation. Apical archaeopyle with two opercula.
Dimensions: holotype 46:31 µm. Other (10) specimens 31-44 µm long, 20-31 µm wide.
Affinities: Wille and Gocht, 1979, p. 238
C. perpunctatum differs from C. stipulatum in its at most 1 Ám high coni, from C. punctatum in that the coni are more numerous and mostly irregularly scatterd and in that also the cingular are is bearing coni.
