Globigerinoidesella fistulosa Similar to the T. sacculifer plexus, G. fistulosa has also undergone taxonomic change following Spezzaferri et al. (2015). Globigerinoidesella fistulosa had previously been termed Globigerinoides fistulosus under the traditional concept of Globigerinoides. However, Spezzaferri et al. (2015) re-introduced the genus Globigerinoidesella El-Naggar, 1971, to separate forms with extended projections from Trilobatus. Globigerinoidesella fistulosa is a short-ranging morphospecies (mid-Pliocene to early Pleistocene). The restricted biostratigraphical range of G. fistulosa makes it a useful zone fossil in tropical assemblages worldwide, and its last appearance is used to define the base of Zone PT1 (Wade et al. 2011). Its ancestral stock is the T. sacculifer plexus and it is inferred to have arisen gradually from T. sacculifer (e.g. Parker 1967; Kennett & Srinivasan 1983; Chaisson & Pearson 1997). Globigerinoidesella fistulosa sensu stricto is characterized by its ornate, digitate ... : Published as part of Poole, Christopher R. & Wade, Bridget S., 2019, Systematic taxonomy of the Trilobatus sacculifer plexus and descendant Globigerinoidesella fistulosa (planktonic foraminifera), pp. 1989-2030 in Journal of Systematic Palaeontology 17 (23) on page 1991, DOI: 10.1080/14772019.2019.1578831, http://zenodo.org/record/10883327 ...
