Taxonomy

Citation: Dentoglobigerina altispira (Cushman & Jarvis 1936)
Rank: species
Basionym: Globigerina altispira
Synonyms:
Taxonomic discussion: Dentoglobigerina altispira is a very common component of Miocene and Pliocene assemblages, first appearing in lower Miocene Subzone M1b (Kennett and Srinivasan, 1983; Chaisson and Leckie, 1993; Spezzaferri, 1994). This species descended from D. globosa in the earliest Miocene, and is distinguished from its ancestor by typically fewer chambers, a higher spire, a deeper umbilicus and slightly more angular chambers. [Wade et al. 2018]

Distinguishing features: High trochospiral. Aperture umbilical with teeth projecting into umbilicus

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.

Description


Diagnostic characters: High trochospiral. Aperture umbilical with teeth projecting into umbilicus

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]
D. altispira shows a bias toward sinistral coiling, this is initially a weak bias (ca 65:35%) but becomes stronger though the Middle Miocene (Winter & Pearson 2001).

Most likely ancestor: Dentoglobigerina globosa - at confidence level 3 (out of 5). Data source: Kennett & Srinivasan 1983; Wade et al. 2018 f11.1.

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 M1b subzone (21.12-22.44Ma, base in Aquitanian stage). Data source: Kennett & Srinivasan 1983; Wade et al. 2018 f11.1

the images from the fox/Norris paper don't look like altispira?!

Hmm. I am not an expert but those are definitively identified specimens by expert taxonomists (and I have just checked to make sure the images have not got mixed up). It is perhaps a bit unfortunate that relatively few of the images show the characteristic side view but I think they are all altispira
