Taxonomy:
Citation: Ceratolithus? atlanticus Perch-Nielsen, 1977Rank: SpeciesTaxonomic discussion: Ornate form, very rare. Described from NN12, but similar specimens from NN9 have been illustrated by Raffi and Flores (1995 p279, plate 4, figs 5-7), Raffi et al. (1998) and Young (1998)
Distinguishing features: complex ceratoliths with spines extending from arch
