Distinguishing features: BCs minute, 0.5-0.7µm, flattened


Morphology remarks: BCs minute (0.5-0.7 µm) only partially calcified, there is an outer ring of rhombohedral crystallites and inner cone of crystallites (usually collapsed), with gap between. CFCs with high arch ending in point (total height 1.5-2 µm), base similar to that of BCs.

Biology & life-cycles: A single possible combination coccosphere of this holococcolith with Syracosphaera marginaporata was illustrated by Cros & Fortun_o (2002, p. 59, fig 112).
