Classification: Coccolithophores -> Coccolithales -> Coccolithaceae -> Bramletteius
Sister taxa: Coccolithus, Bramletteius, Campylosphaera, Chiasmolithus, Coronocyclus, Cruciplacolithus, Ericsonia, Solidopons, Birkelundia, Clausicoccus, Craticullithus, Hughesius, Kilwalithus,

Daughter taxa: (blue => in age window 0-800Ma)

Like B. serraculoides but spine narrower, and stratigraphically older

Small Cruciplacolithus-like coccoliths with tall, thin, paddle-like processes.
Specimens which cannot be assigned to any established species


Citation: Bramletteius Gartner, 1969
Rank: Genus
Type species: Bramletteius serraculoides Gartner, 1969
Notes & discussion: Bramletteius variabilis Roth, 1970 was described based on differently shaped spines (e.g. ), but only Bramletteius serraculoides is routinely reported.
A Pliocene species Bramletteius? duoalatus Martin 1981 is probably an unusual Gepyrocapsa

Distinguishing features: Like Cruciplacolithus but coccoliths small and with large, thin, paddle-like processes.
