NB Globorotalia pseudomiocenica Bolli and Bermudez was also considered a synonym by Blow (1969) & Kennett & Srinivasan (1983), but is now regarded as discrete species.
Catalog entries: Rotalia limbata, Globorotalia praemiocenica
Type images:Distinguishing features:
Parent taxon (menardii lineage): G. archeomenardii - menardii, limbata - miocenica & exilis - pertenius lineages
This taxon: Like G. menardii but uniformly increasing chambers in the final whorl; spiral sutures, initially straight then become sharply curved near the periphery, giving a hockey-stick shape

Phylogenetic relations
Gr. (M.) limbata evolved from Gr. (M.) menardii and is the ancestor of Gr. (M.) multicamerata. [Kennett & Srinivasan 1983]
Most likely ancestor: Globorotalia menardii - at confidence level 4 (out of 5). Data source: Kennett & Srinivasan 1983, fig. 14; Stewart 2003 fig. 6.10; Aze et al. 2011, appendix 5.
Likely descendants: Globorotalia exilis; Globorotalia multicamerata; Globorotalia pseudomiocenica;

Geological Range:
Last occurrence (top): at top of PL5 [Atl.] zone (100% up, 2.4Ma, in Gelasian stage). Data source: Wade et al. (2011), zonal marker
First occurrence (base): near top of M11 zone (87% up, 10.6Ma, in Tortonian stage). Data source: Wade et al. (2011), additional event; position within zone determined by linear interpolation from data in table 1 of Wade et al. (2011).
