Phylogenetic relations
Most likely ancestor: Pulleniatina praespectabilis - at confidence level 2 (out of 5). Data source: Aze et al., 2011, Bronnimann & Resig 1971 (NB Kennett & Srinivasan 1983 did not differentiate praespecatbilis).
Geological Range:
Last occurrence (top): in lower part of PL2 zone (31% up, 4.2Ma, in Zanclean 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).
First occurrence (base): within N18 zone (5.20-5.72Ma, base in Messinian stage). Data source: Kennett & Srinivasan 1983
