Citation: Globanomalina chapmani (Parr 1938)
Rank: Species
Basionym: Globorotalia chapmani
Taxonomic discussion: Haig et al.'s (1993) illustrations of the holotype, paratypes, and topotypes taken by SEM has clarified the morphologic characters of this species. It is clear from these illustrations that Anomalina luxorensis Nakkady (1951), Globanomalina ovalis var. lakiensis Haque (1956), the form identified by Subbotina (1953, pl. 16: fig. 12a-c) as Globorotalia membranacea (Ehrenberg, 1854), and the form identified by Bolli (1957a, pl. 20: figs. 11-13) as Globorotalia elongata (Glaessner, 1937a) should be placed in the synonomy of G. chapmani. In addition, Globorotalia troelseni Loeblich and Tappan (1957a) and the form identified by Hillebrandt (1962, pl. 12: fig. 3a-c) as Globorotalia ehrenbergi Bolli (1957a) are 5-chambered, compressed, smooth-walled forms that can be
placed in G. chapmani. Globanomalina chapmani is a common species in upper Paleocene assemblages. [Olsson et al. 1999]

Type images:

Distinguishing features: Test compressed, periphery pinched with a thickened imperforate band. 5-6 rapidly enlarging chambers in final whorl.

NB These concise distinguishing features statements are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus.
They are being edited as the site is developed and comments on them are especially welcome.


Diagnostic characters: This species is identified by its compressed test, pinched periphery with a thickened imperforate band, and the rapidly enlarging chambers. The number of chambers in the ultimate whorl is typically 5 but can range up to 6. The test walls are smooth with occasional small pustule buildups in the umbilical area and on the inner spiral area. [Olsson et al. 1999]

Biogeography and Palaeobiology

Geographic distribution: Worldwide in the middle and high latitudes. [Olsson et al. 1999]
Aze et al. 2011 summary: Cosmopolitan in middle to high latitudes; based on Olsson et al. (1999)

Isotope paleobiology: Globanomalina chapmani has ∂18O and ∂13C similar to Parasubbotina varianta, S. triloculinoides, and G. pseudomenardii. The species has distinctly more positive ∂18O and more negative ∂13C than Morozovella ,Acarinina,and Igorina. [Olsson et al. 1999]
Aze et al. 2011 ecogroup 3 - Open ocean thermocline. Based on light δ13C and relatively heavy δ18O. Sources cited by Aze et al. 2011 (appendix S3): Olsson et al. (1999)

Phylogenetic relations: Globanomalina chapmani is a member of the smooth-walled imperforate periphery lineage and evolved from G. ehrenbergi (Bolli) in the lower part of Zone P4. [Olsson et al. 1999]

Most likely ancestor: Globanomalina ehrenbergi - at confidence level 4 (out of 5). Data source: Olsson et al. 1999, fig 5a.
Likely descendants: Globanomalina planoconica;
