Classification: pf_cenozoic -> Guembelitrioidea -> Guembelitriidae -> Woodringina
Sister taxa: Cassigerinelloita, Globoconusa, Guembelitria, Jenkinsina, Parvularugoglobigerina, Woodringina

Daughter taxa (time control age-window is: 0-800Ma)

			Woodringina claytonensis Test triserial initially then biserial, twisted with 5 or less chambers pairs. Apertural height appears to vary from high to low.
			Woodringina sp. Specimens which cannot be assigned to established species

Taxonomy

Citation: Woodringina Loeblich and Tappan, 1957

Rank: Genus

Type species: Woodringina claytonensis Loeblich and Tappan, 1957b.

Taxonomic discussion: Although Woodringina remains limited to the Paleocene, it is no longer monotypic. It was assigned to the subfamily Guembelitriinae by Loeblich and Tappan (1957b). Elevation of the subfamily Guembelitriinae to the family Guembelitriidae (El-Naggar, 1971; Blow, 1979; Loeblich and Tappan, 1988) removed it from the family Heterohelicidae. [Olsson et al. 1999]

Catalog entries: Woodringina

Distinguishing features:
Parent taxon (Guembelitriidae): Tests triserial, trochospiral, or nearly triserial in initial whorl becoming biserial. Chambers usually globular or subglobular, increasing gradually in size. Aperture usually a loop-shaped arch, often slightly infolded on one side, marked by a fine lip.
This taxon: Tests contain an initial whorl of 3 chambers, later whorls of 2 chambers each. Test wall microperforate, marked by a guembelitriid surface texture (smooth walled or bearing perforate pustules). Aperture usually asymmetrically positioned and thin apertural lip infolded on one side.

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.

Biostratigraphic distribution

Geological Range:
Last occurrence (top): in lower part of Selandian Stage (37% up, 60.7Ma, in Selandian stage). Data source: Total of range of species in this database
First occurrence (base): at base of Danian Stage (0% up, 66Ma, in Danian stage). Data source: Total of range of species in this database

Plot of occurrence data:

Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
Triangles indicate an event for which a precise placement has been suggested
Neptune data: This is a higher taxon page so Neptune data is not plotted. See also: customisable plot Parent: Guembelitriidae

thanks, I've added the Woodringina paper, but I've left the book as 1988 since it is cited as that in numerous places on this site and elsewhere.
