Classification: Coccolithophores -> Nannolith families inc sed -> Ceratolithaceae -> Ceratolithus -> Ceratolithus larrymayeri
Sister taxa: C. apiculus, C. armatus, C. atlanticus, C. cristatus, C. larrymayeri, C. separatus, C. sp.,


Citation: Ceratolithus larrymayeri Backman & Raffi, in Raffi et al. 1998
Rank: Species
Notes & discussion: Possibly related to C. atlanticus, which has highly variable morphology and similar stratigraphic range. Also rather similar to C. armatus in shape of apical area.

Distinguishing features: Delicate ceratolith with thin arms and apical spine; featureless surface.
