Kiokansium perprolatum
Kiokansium perprolatum Singh, 1983
Holotype: Singh, 1983, pl.54, fig.7
Locus typicus: Dunvegan Formation of the Peace River area
Stratum typicum: Middle Cenomanian
Original description: Singh, 1983, p. 150
Skolochorate cysts; central body perprolate, ellipsoidal, and about twice as long as wide; autophragm thin, smooth, and single layered; central body bearing 60 or more, uniformly distributed, nontabular, and slender processes; stems of the processes 0.5 to 1 Ám wide and flexible; tips of the processes closed, flared, and forming small, umbrella-like, membranous structures fringed with up to 5 Ám long, straight or recurved spinules; length of the processes from 1/5 to 1/3 of the length of the central body; archeopyle precingular, type 2P; operculum free, often remaining in place.
Size range: Overall length including the processes 90(101)120 Ám. Holotype 108 Ám. Overall breadth including the processes 54(66)76 Ám. Holotype 61 Ám. Length of the central body 68(77)89 Ám. Holotype 89 Ám. Breadth of the central body 36(40)44 Ám. Holotype 40 Ám. Length of the processes 18(20)24 Ám. Holotype 18 to 22 Ám. Specimens measured 6.
Affinities:
Singh, 1983, p. 151: Kiokansium perprolatum differs from Kiokansium williamsii in being distinctly larger and having a more elongate central body which is usually twice as long as wide.
