Psilochara sp.

( Fig. 11G–I)

Material. Seventeen gyrogonites in sample G-6a. Collection numbers of figured specimens: HNHM-PBO 1570–1571.

Description. Medium- to large-sized gyrogonites (780–905 M m wide and 670–775 M m high) with elongated ovoidal (sub-prolate) shape ( ISI 110–125) and laterally showing 8–10 convolutions ( Fig. 11G). Apex truncated. Apical end of spiral cells enlarged and pointing upwards ( Fig. 11H). Base truncated to somewhat tapering, bearing a small pentagonal basal pore. Basal plate unipartite and visible from the gyrogonite interior ( Fig. 11I). Spiral cells concave or flat and smooth, except at the periapical area, where they are irregularly ornamented with a broad mid-cellular crest.

Remark. The low number of gyrogonites hinders a more precise taxonomic attribution of this population. However, it is reported here since it differs in size and shape from the other species of Psilochara found at Ǵant.
