Acicularia sp. 2

Fig. 4 View Fig j-k

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).
