Palusphaera crosiae


Classification: ntax_cenozoic -> Syracosphaerales -> Rhabdosphaeraceae -> Palusphaera -> Palusphaera crosiae
Sister taxa: P. vandelii, P. probertii, P. crosiae, P. bownii, P. sp.

Taxonomy:

Citation: Palusphaera crosiae Archontikis & Young 2021
Taxonomic rank: species
Synonyms:
Taxonomic discussion: Cros & Fortuño (2002) suggeted that this was  probably a separate species. This has been confirmed by examniation of further species - see Archontikis & Young 2021.

Distinguishing features:
Parent taxon (Palusphaera): Coccoliths without radial lath cycle; coccospheres monomorphic, all spine-bearing
This taxon: Form with robust spines and maximum spine thickness approximately 1/3 up spine.
