Citation: Tenuitellita parkerae (Brönnimann & Resig, 1971)

Basionym: Globorotalia (Turborotalia) parkerae Brönnimann & Resig, 1971

Synonyms:

Tenuitella parkerae (Brönnimann & Resig, 1971)
Globorotalia parkerae (Brönnimann & Resig, 1971)

Distinguishing features:
Parent taxon (Tenuitellita):
This taxon: Five radially elongate chambers

Description

Tenuitellita parkerae is characterized by smooth wall texture and a tendency to grow radially elongated and slightly compressed chambers (Holmes, 1984, Brummer 1988 p.106), explaining why the species has also been assigned to the macroperforate Globorotalia (e.g. by Saito et al., 1981). [Brummer & Kucera 2022]

Coiling direction (in extant population): mixed

Biogeography and Palaeobiology
