Description: Coccolith structure similar to that of Coccolithus, but central area spanned by disjunct axial cross.

Cruciplacolithus is not usually recorded from the Neogene but in well-preserved samples Cocolithus specimens with central crosses are quite frequent. Also small Cruciplaclithus specimens can occoasionlly be found, as illustrated here from the Pliocene:
