Calciosolenia fossilis


Classification: ntax_mesozoic -> Syracosphaerales -> Calciosoleniaceae -> Calciosolenia -> Calciosolenia fossilis
Sister taxa: C. fossilis, C. huberi, C. sp.

Distinguishing features: Minute to small, long and narrow rhombic muroliths with a central area spanned by numerous transverse bars.


Taxonomy:

Citation: Calciosolenia fossilis (Deflandre in Deflandre & Fert, 1954) Bown in Kennedy et al., 2000
Rank: Species
Basionym: Scapholithus fossilis Deflandre in Deflandre & Fert, 1954
Taxonomic discussion: Deflandre in Deflandre & Fert, 1954 proposed the generic name Scapholithus for fossil ‘scapholith’ coccoliths but these are indistinguishable from the extant representatives classified within Calciosolenia Gran, 1912. The species name, fossilis, is used in a broad sense, as the coccoliths are generally small and difficult to differentiate at species level, Calciosolenia sp. would be a more transparent identification.

Distinguishing features: Minute to small, long and narrow rhombic muroliths with a central area spanned by numerous transverse bars.


Morphology: Modern species show significant varimorphism across the coccosphere, typically with longer thinner liths towards the ends of the coccosphere. So, it is not surprising that fossil specimens show analgous variability.
