Georgescu, Marius Dan (2011): A new type of test wall in the Late Cretaceous (late Santonian-Campanian) heterohelicid planktic Foraminifera. Elsevier, Paris, France, Revue de Micropaleontologie, 54 (2), 105-114, georefid:2012-020046

The first Cretaceous serial planktic foraminifer (family Heterohelicidae Cushman, 1927) with simple-ridged test wall is reported from the uppermost Santonian-lower Campanian sediments of the Deep Sea Drilling Project Site 463 (Mid-Pacific Mountains, equatorial Central Pacific). Hendersonites pacificus n. sp. is characterized by the reduced ornamentation over the last pairs of chambers and strong peripheral costae lining the periphery with test wall flexure. This species evolved from H. carinata (Cushman, 1938) of the upper Santonian-Campanian, a frequently reported species from the Atlantic Ocean, Gulf of Mexico and Western Tethyan Realm.
