Papposphaera cf. lepida Tangen 1972

A-B = Papposphaera-stage, diameter=17 µm (A=PC, B=DIC); C-D = Turrisphaera-stage (found in the same sample as A-B), C = Coccosphere, diameter=15 µm (PC); D = Schematic drawings of coccoliths. All dry preparations


Life-form: Solitary

Size: Coccosphere diameter = 11-16 µm, cellbody = 4.5-7.0 µm

Resting spore:

Note: Best studied in TEM. The relationship between Papposphaera and Turrisphaera is discussed in Thomsen et al. (1991)

Distinctive features: Monomorphic styliform pappoliths

Similar species: Papposphaera thomsenii

Distribution: Worldwide
