Catalog entries:
Distinguishing features:
Parent taxon (Globigerinidae): Wall spinose, usually with 3½-6 globular chambers in final whorl, trochospiral or planispiral
This taxon: Like Globigerinella but adult chambers radially elongate. (Oligocene - Mid Miocene)

Phylogenetic relations
Most likely ancestor: Globigerinella - at confidence level 2 (out of 5). Data source: Spezzaferri et al. 2018, p208.
Geological Range:
Notes: The stratigraphic range of Quiltyella is uncertain because its occurrence is extremely sporadic. Based on the limited data we suggest it ranges from the lower Oligocene Zone O4 to somewhere in the lower or middle Miocene (Quilty, 1976).
Last occurrence (top): at top of M4 zone (100% up, 16.4Ma, in Burdigalian stage). Data source: Total of ranges of the species in this database
First occurrence (base): within O4 zone (28.09-29.18Ma, base in Rupelian stage). Data source: Total of ranges of species in this database
