Taxonomy:

Citation: Scyphosphaera interstincta Bown & Newsam 2017
Rank: Species

Distinguishing features: Elongate barrel-shaped, with distinct wall ornament of large pits or pores.

Farinacci & Howe catalog pages: Scyphosphaera interstincta * ,


Morphology remarks: Elongate-barrel shaped Scyphosphaera with distinct wall ornament of large pits or pores. The coccolith wall tapers gently both proximally and distally, and the inner cycle thickens at the distal opening.
Differentiation: Distinguised from other Scyphosphaera by the wall ornament and inner cycle thickening at the distal opening. [Bown & Newsam 2017]

Size: Holotype L/W = 7.7μm; H = 14.3μm (Paratype L/W = 8.3μm; H = 14.3μm). Holotype L/W = 6.1μm; H = 11.3μm [Bown & Newsam 2017]
