Solisphaera miocaenica


Classification: ntax_cenozoic -> Syracosphaerales -> Rhabdosphaeraceae -> Solisphaera -> Solisphaera miocaenica
Sister taxa: S. blagnacensis, S. emidasia, S. helianthiformis, S. galbula, S. turbinella ⟩⟨ S. tegula, S. palmula ⟩⟨ S. miocaenica, D. moori, S. sp.

Taxonomy:

Citation: Solisphaera miocaenica (Müller 1974 ) Young 2023
taxonomic rank: species
Basionym: Calyptrosphaera miocaenica Müller 1974
Taxonomic discussion: This species was described from Early Miocene paratethyan deposits and interpreted as a holococcolith. The type illustrations, however, show marked similarity to Solisphaera equatorial coccoliths, including the flattened form, presence of a basal disk and hints of similar fabric to the domal struture. [my interpretation - JRY 2016]

Distinguishing features:
Parent taxon (Solisphaera): Coccoliths without radial lath cycle; coccosphere dome-shaped, polymorphic
This taxon: CCs similar to S. blagnacensis, but with papilla at top; BCs not known (Miocene)
