Woodringina


Classification: pf_cenozoic -> Guembelitrioidea -> Guembelitriidae -> Woodringina
Sister taxa: Cassigerinelloita, Globoconusa, Guembelitria, Jenkinsina, Parvularugoglobigerina, Woodringina,
Daughter taxa: (blue => in age window 0-300Ma)
Test biserial, elongate, tapering with 6 or more chamber pairs, distinctly twisted. Wall microperforate. Aperture with a thin lip. Apertural position and height are somewhat variable.
Test triserial initially then biserial, twisted with 5 or less chambers pairs. Apertural height appears to vary from high to low.
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;

Type images:

Distinguishing features: 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.

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.
