Clathrolithus ellipticus


Classification: ntax_cenozoic -> Holococcoliths -> fossil holococcoliths -> Clathrolithus -> Clathrolithus ellipticus
Sister taxa: C. arenarius, C. ellipticus, C. joidesa, C. minutus, C. sp.

Taxonomy:

Citation: Clathrolithus ellipticus Deflandre in Deflandre & Fert, 1954
Rank: Species
Synonyms:
Taxonomic discussion: These holococcoliths have complex three-dimensional structure and exhibit high variability including plate-like and domed forms. Distinguished by the diagnostic raised ridges in LM.

Distinguishing features: Large, solid, elliptical and ‘C’-shaped holococcoliths that have honeycomb-like ridges on one surface.
