Remarks: In the studied thin-sections, this morphotype is less frequent than Acicularia sp. 1. It is more slender and exhibits spherical cysts (diameter 0.06-0.10 mm). Similar sections have been illustrated from the Thanetian Bekrit-Timahdit Formation of Morocco (Kuss and Herbig, 1993, pl. 6, fig. 17).
