Michaelsarsia elegans


Classification: ntax_cenozoic -> Syracosphaerales -> Syracosphaeraceae -> Michaelsarsia -> Michaelsarsia elegans
Sister taxa: M. adriaticus, M. elegans, M. sp.

Taxonomy:

Citation: Michaelsarsia elegans Gran, 1912
Rank: Species
Synonyms: NB It is not really possible to tell with any of these early descriptions if the taxon illustrated is M. elegans or M. adriaticus as currently understood but there is no reason to change the established nomenclature.

Distinguishing features:
Parent taxon (Michaelsarsia): Coccosphere with apical appendages formed from string of three highly-modified coccoliths, supported by whorl coccoliths
This taxon: BCs elliptical; whorl and link coccoliths with wide opening

Farinacci & Howe catalog pages: M. elegans * , H. vahseli * , M. splendens * , M. falklandica * , M. asymmetrica *


Morphology:

BCs - long elliptical; rim broad; axial structure is prominent mound, about 1/3 width of coccolith.
CFCs - spine solid or with narrow central canal.
Whorl coccoliths - with wide opening.
Link coccoliths - broad, sides well separated.
