Van Eijden & Smit (1991):
Remarks. G. sellii is usually rare and is connected with G. binaiensis Koch, 1935 and G. tripartita Koch, 1926 by intermediate forms.
Quilty (1976):
Remarks: The oldest true G. sellii from Leg 34 occurs in 321-9.CC. Below that depth, several identifications are recorded on the range charts as G. cf. sellii and strictly probably refer to specimens internee tapuriensis-sellii. This evolutionary sequence suggests that the true base of P19 is accurately placed in 321-9, CC. The top of the range of G. sellii is not N3 as indicated by Blow (1969). In Leg 34 material, and in material from oil exploration wells
in northwestern Australia, G. sellii occurs into N4, earliest Miocene. |
