Distinguishing features: Central area with diagonal cross
Process ca. 0.5-1.5 µm, robust with calyx of three or four rods.
Dimorphic: CFCs with tall processes (ca. 1.5 µm) with calyx of 4 (or 3?) rods perpendicular to process. BCs with shorter processes and calyx of 3 diverging rods.

Data source notes: csph & lith size (BC diameter) from Cros & Fortuño 2002 & slightly extended
Last occurrence (top): Extant Data source: present in the plankton (Young et al. 2003)
First occurrence (base): within No known fossil record modern (0.00-0.00Ma, base in "Holocene" stage). Data source: [JRY rough estimate]
Plot of occurrence data:
- Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
- Triangles indicate an event for which a precise placement has been suggested
- (NB There is no histogram as there are no occurrence records for the taxon in the Neptune database) Parent: Papposphaera
