Farinacci & Howe catalog pages: Watznaueria cynthae *
Distinguishing features: Broadly elliptical with two variably developed central pores that pierce the inner cycle.
Morphology remarks: These coccoliths resemble Watznaueria biporta Bukry, 1969, but are more subcircular in outline and do not routinely display clear pores.
