Farinacci & Howe catalog pages: Craticullithus clathrus *

Short diagnosis: Medium to large, elliptical placolith coccoliths with broad central-areas spanned by lattice-like grills that are dominated by longitudinal bars.

Morphology remarks: The distal shield elements show distinctly kinked and stepped sutures. Approximately 12 lath-like bars make up the central grill with one to four central transverse bars and three to five longitudinal bars forming the rest of the structure.
