Shublikodinium verrucosum var. verrucosum
Shubikodinium verrucosum var. verrucosum
Autonym. Now redundant.
Holotype: Wiggins, 1973, pl.3, fig.3
Locus typicus: North Slope of Alaska
Stratum typicum: Late Triassic
Original diagnosis: Wiggins, 1973, p.5: Shubikodinium verrucosum
Same as for the genus with the following additional description, The cyst wall of this variety is covered with a verrucate ornamentation which is very similar to that noted on S. verrucosum, The outer wall pattern of ornamentation is embossed, and only a couple of fragmental hypotracts were encountered with this type of outer wall surface. This embossed pattern appears to be superimposed on, and not coincident with, the normal sutural tabulation pattern of the hypotract. Also, it superficially gives an appearance of fewer, raised hypotractal plates, with wide depressions in between. Some specimens of S. verrucosum (plate 4, figure 1) trend toward this condition with a slightly embossed wall feature covering more than one hypotractal plate. Dimensions: Holotype: over-all length 44 µm over-all width 44 µm transverse furrow width approximately 5-6 µm.
