Halldal (1953) Heimdal, in Heimdal & Gaarder 1980 ? = S. histricaHOL
Calyptrosphaeraceae (this is an artificial grouping -heterococcolith phase is currently un-confirmed)
After Young et al. 2003. BCs tube about 9 crystallites high, no flange; distal surface flat; hexagonal mesh fabric to tube and distal cover. Liths ca. 2 μm long.
CFCs vaulted with flat hexagonal mesh plates sloping towards centre from each end. Between these plates an irregular area of parrallel strings of crystallites occurs.
Sub-tropical (Findlay & Giraudeau, 2000).
Between 57°12' S, 155°23'E and 58°49' S, 152°48'E, L. Harding, AAD, unpub.
After Young et al. Life-cycle: Based on holococcolith morphology one might predict an association with a Coronosphaera species, however a possible combination coccosphere with Syracosphaera histrica was shown by Cros et al. (2000).
