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


Citation: Woodringina Loeblich&Tappan, 1957
taxonomic 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.

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.
