Subspecies Globorotalia (Turborotalia) opima nana Bolli 1957


Alternative name:
Globorotalia opima nana Bolli 1957
Discussion / Comments:
Quilty (1976):
Remarks: As well as typical G. (T.) o. nana, a form is figured which has the typical coiling pattern but has a reduced ultimate chamber, more open umbilicus, and no obvious development of a strong apertural lip. In all aspects other than coiling patterns, it is very like G. (T.) o. opima.
