Kenleyia leptocerata
From Fensome et al., 2019:
Kenleyia leptocerata Cookson and Eisenack, 1965b, p.136, pl.17, figs.5–6. Holotype: Cookson and Eisenack, 1965b, pl.17,
fig.6. Age: Paleocene.
---------------------------------------------------------------------------------------------------
Original description: Cookson and Eisenack, 1965, p.136
Shell oval, thin-walled, outer layer finely granular, girdle equatorial bordered by low, fibrillose ledges; apical horn short, broadish and blunt, antapical horn longer, tapering from base to apex, tip frequently upwardly curved. Accessory apical outgrowths clear in the holotype (Pl. 17, fig. 6) more often poorly developed or fibrillose as also are those of the antapex; fibrillose outgrowths may be present on other portions of the shell. Archeopyle large, trapezoid, straight-sided, extending from just behind the apex almost to the girdle.
Dimensions: Holotype--overall length c. 102 µm, overall width c. 76 µm; shell c. 78 x 62 µm. Range--overall length c. 100-112 µm, overall width c. 76-85 µm; shell c. 70-82 µm x 62-75 µm; antapical horn c. 22 µm long.
