Lamprothamnium sp. (Fig. 6 I-L) DESCRIPTION Medium-sized gyrogonites, 432-648 μm high (mean 547 μm) and 297-513 μm wide (mean 434 μm), elongate, prolate to sub-cylindrical in shape, with an isopolarity index ranging from 111-163 (mean 127). Apex lamprothamnoid, truncated, showing a marked periapical depression due to decreasing cell thickness. Ŋe base is rounded with a small basal pore (45 μm). Spiral cells flat to convex, without ornamentation. Eight to ten (frequently nine) convolutions are visible in lateral view.
