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.


Diagnostic characters: High trochospiral

Aperture: Umbilically restricted with umbilical teeth projecting into umbilicus [Aze 2011, based on Kennett & Srinivasan 1983]

Wall type: Non-spinose; Cancellate [Aze 2011]

Test morphology: Test large, high trochospiral, four to five chambers in the final whorl, initially subspherical, latter chambers appressed, prolonged toward umbilicus ; chambers increase moderately in size as added; sutures on spiral side slightly curved to radial, depressed; on umbilical side radial, depressed; surface distinctly cancellate; umbilicus wide, open, deep; aperture umbilically restricted, with umbilical teeth projecting into the umbilicus. [Kennett & Srinivasan 1983]

Biogeography and Palaeobiology

Geographic distribution: Tropical to warm subtropical. [Kennett & Srinivasan 1983] Low latitudes [Aze et al. 2011, based on Kennett & Srinivasan (1983)]

[SCOR WG138]

Isotope paleobiology: Aze et al. 2011 ecogroup 1 - Open ocean mixed-layer tropical/subtropical, with symbionts. Based on very heavy ∂13C and relatively light ∂18O. Sources cited by Aze et al. 2011 (appendix S3): Pearson et al. (2001b)

Phylogenetic relations:

D. altispira altispira evolved from D. altispira globosa by developing a distinctly high trochospire and laterally compressed and umbilically prolonged chambers in the final whorl. [Kennett & Srinivasan 1983]

Biostratigraphic distribution

Geological Range:
Last occurrence (top): at top of PL4 [Atl.] zone (100% up, 3.1Ma, in Piacenzian stage). Data source: Wade et al. (2011), zonal marker - but occurs earlier in the Pacific
First occurrence (base): within N4b zone (22.20-23.50Ma, base in Chattian stage). Data source: Kennett & Srinivasan 1983
