Pareodinia groenlandica
Pareodinia groenlandica Sarjeant, 1972
Holotype: Sarjeant, 1972, pl.5, fig.1
Locus typicus: Jameson Land, Greenland
Stratum typicum: Late Bathonian-Early Callovian
Original diagnosis: Sarjeant, 1972, p.27
A species of Pareodinia having an ovoid cyst, prolonged at the apex into a stout, blunt horn. The length of the horn is between one-quarter and one-third the length of the central body; it is formed from both wall layers, not by the periphragm only. The wall is relatively thick: the surface of the periphragm exhibits a dense network of areolae.
Dimensions:
Holotype: overall length 73 µm, breadth 44.5 µm, length of apical horn 17 µm, Range overall length 64 - 84 µm (mean 73. 8 µm), breadth 38 - 56 µm (mean 46. 5 µm), length of apical horn 12 - 21 µm (mean 17.1 µm).
