Helicosphaera burkei Black 1971
Helicolith has a Type III (Helicosphaera carteri type) blanket, an expanded flange termination and a non-perforated proximal plate. Helicosphaera burkei exhibits inclined extinction angles of about 55° on the blanket on the distal side and shows length-fast (−) elongation.
Helicosphaera burkei differs from Helicosphaera carteri by having a non-porous central area, whereas the latter has two pores in the central area
