Taxonomy:

Citation: Discorhabdus patulus (Deflandre in Deflandre & Fert, 1954) Noël, 1965
Rank: Species
Basionym: Rhabdolithus patulus Deflandre in Deflandre & Fert, 1954

Farinacci & Howe catalog pages: Rhabdolithus patulus * , ,

Distinguishing features: Placoliths with a tall flaring spine.


Morphology remarks: The type material comprises side views only and so it is difficult to ascertain whether these coccoliths are discorhabdids or podorhabdids. In the same publication, Noël (1965) described a similar cocccolith as Podorhabdus grassei but also designated Rhabdolithus patulus Deflandre, 1954, as the type species of Discorhabdus by Noël (1965).
