Classification: pf_neogene -> Globorotalidae -> Pulleniatina
Sister taxa: Berggrenia, Dentigloborotalia, Dentoglobigerina, Globoconella, Globoquadrina, Globorotalia, Globorotaloides, Neogloboquadrina, Pulleniatina,

Distinguishing features: Compact streptospiral test with smooth cortical coating and large slit-like aperture

Daughter taxa (blue => in age window 0-300Ma)
primalis -> obliquiloculata lineage
Like P. obliquiloculata but more involute, aperture wider, fewer chambers in final whorl (4 vs 4-5)
Test globose, rounded, aperture extending from umbilical area to periphery and onto spiral side.
Like P. primalis but aperture extends onto the periphery of the previous whorl
Aperture restricted to the umbilical side
praespectabilis -> spectabilis lineage
Like P. praespectabilis but pseudocarina (pinched shoulder) on final whorl, and dorsal surface flatter
Like P. primalis but more plano-convex with distinct, rounded, peripheral shoulder
Specimens which cannot be assigned to established species


Citation: Pulleniatina Cushman 1927
Rank: genus
Type species: Pulleniatina obliquiloculata Parker & Jones 1865
Taxonomic discussion: Pulleniatina includes forms with trochospiral to streptospiral coiling, a subglobular test encrusted with a thick cortex, and an aperture that is interiomarginal, umbilical-extraumbilicalin position. This genus resembles Globigerina in early development but differs in exhibiting later streptospiral coiling and an embracing final chamber with characteristic extraumbilical peripheral aperture and thick cortex. Until 1964, the genus Pulleniatina was considered monotypic, represented only by the type species P. obliquiloculata (Parker and Jones). However, detailed work by Banner and Blow (1967) on the evolution of this genus revealed greater taxonomic diversity and complexity. [Kennett & Srinivasan 1983]

NB The short diagnoses are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus. They have initially been copied from the diagnostic characters/distinguishing features sections of the Eocene and Paleocene Atlases, they will be edited as the site is developed.


Biogeography and Palaeobiology

Phylogenetic relations: The earliest member of the Pulleniatina lineage, P. primalis, evolved from N. acostaensis at the base of Zone N17B at about 6.2 Ma and provides a useful datum (Srinivasan and Kennett, 1981a). P. primalis seems to have evolved within two separate lineages: (1) P. primalis to P. praecursor to P. obliquiloculata and (2) a relatively short-lived, geographically restricted lineage from P. primalis to P. spectabilis (Text Fig. 22). [Kennett & Srinivasan 1983]

Most likely ancestor: Neogloboquadrina - at confidence level 3 (out of 5). Data source: Kennett & Srinivasan 1983.
