Ericiolus frigidus


Classification: ntax_cenozoic -> Nannolith families inc sed -> Nannolith genera inc sed -> Ericiolus -> Ericiolus frigidus
Sister taxa: E. aspiphorus, E. multistellatus, E. pusillus ⟩⟨ E. frigidus, E. spiculiger ⟩⟨ E. bendifii, E. mattioliae, E. sheldoniae, E. sp.

Taxonomy:

Citation: Ericiolus frigidus Thomsen in Thomsen et al., 1995
taxonomic rank: Species
Synonyms: ‘Coccolithophorid sp. 2’ in Thomsen et al. 1988

Distinguishing features:
Parent taxon (Ericiolus): Nannoliths, miniscule (<1 µm), formed of 3 nearly co-planar rays, often with a distal process. Cells monomorphic, often saddle-shaped, with long flagella and haptonema.
This taxon: All four spikes of tetrad of similar length (0.2-0.3 µm) and angles between all four are equal.
