Citation: Wigwamma Manton et al., 1977Rank: GenusType species: Wigwamma arctica Manton et al. 1977Taxonomic discussion: Wigwamma was excluded from the Papposphaeraceae by Andruleit & Young (2010) and is only very tentatively included here.
Distinguishing features: Coccoliths hoop-shaped with rods rising from rim to form wigwam-like structure
