Rank: species
Basionym: Globigerina altispira
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.
They are being edited as the site is developed and comments on them are especially welcome.


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

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

Cushman and Jarvis (1936) wrote that Globigerina altispira n. sp. has "about five" chambers in the final whorl. The type illustration definitely shows five. Fox and Wade (2013), however, limited Dentoglobigerina altispira to specimens with four chambers in the last whorl, placing those with 5-6 in D. globosa (Bolli, 1957). Wade et al. (2018) wrote that D. altispira "descended from D. globosa in the earliest Miocene, and is distinguished from its ancestor by typically fewer chambers." These authors did not, however, illustrate D. altispira. I guess we shall have to await a definitive study of Miocene planktonic forams to resolve this issue.

Hi Brent - As you say the holotype definitely has 5 chambers so it is not possible to define altispira as only including specimens with 4 chambers. However, the full quote from Wade et al. 2018 (Oligocene Atlas) is "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." So this leaves space for the holotype to stay in altispira, but for most altispira specimens to have 4 chambers. I suspect though that you are right and the line will be revisited by the Neogene working group. Jeremy


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

Jeremy Young (Tonbridge, UK)

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
