i2 4 UPPER CRETACEOUS-LOWER TERTIARY FOR AMINI FER A 



Remarks. Marie (1941) described Rosalinella globigerinoides as a new species 

 from the Campanian, " Belemnitella mucronata chalk " of the Paris Basin. As 

 Rosalinella Marie, is a junior synonym of Globotruncana Cushman 1927, the name of 

 the present species was automatically changed to Globotruncana globigerinoides 

 (Marie) where it became a junior homonym of Globotruncana globigerinoides Brotzen 

 1936, which in its turn is a junior synonym of G. cretacea (d'Orbigny) 1840. 



Gandolfi (1955) changed the name of the present species to Globotruncana mariai 

 nom. nov. Apparently he named the species after Dr. P. Marie, who first described 

 it, and the spelling should have been mariei. Unfortunately, Banner & Blow (i960) 

 proposed the name G. mariei for G. cretacea Cushman 1938, which itself is a junior 

 homonym of G. cretacea (d'Orbigny) 1840. 



As neither of the names can be changed according to the rules of zoological 

 nomenclature, they are both applied here in spite of the confusion which may result. 



Globotruncana mariai is distinguished by its peculiarly shaped, segmented, imbricate 

 double keel and wide peripheral band. Marie (1941) also described as R. globi- 

 gerinoides var. sublaevigata, a form which only differs from the central type in having 

 the two marginal keels unequally projecting. Such a minor variation was found to 

 be unworthy of distinction and thus G. globigerinoides var. sublaevigata is included 

 here within the central type. 



Hypotype. P.45547. 



Horizon and locality. Hypotype from sample No. 4, Abou Saboun section. 



Stratigraphical range. This species was originally described from the 



Campanian of the Paris Basin (Marie 1941). It occurs as a rare to common form in 



the Lower Maestrichtian G. fomicata Zone of the studied sections, and dies out 

 completely in the top part of this zone.

Remarks. Globotruncana mariei was first described by Cushman (1931) as 

 Globotruncana area (Cushman). The same author (1938), realizing the difference 

 between this form and G. area, considered it as a distinct species and named it 

 G. cretacea Cushman. 



Tilev (1951, 1952) stated that although Cushman (1938) had described his G. 

 cretacea as " usually having a single keel ", the holotype, as figured by Cushman
