Daughter taxa (time control age-window is: 0-800Ma)		Granddaughter taxa
	Anaticinella	Anaticinella multiloculata Anaticinella planoconvexa Anaticinella sp.
	Biticinella Test with early whorls in a flat trochospiral coil, later whorls planispiral and biumbilicate, involute to partially evolute, sutures radial, depressed, peripheral outline lobulate, peripheral margin rounded and noncarinate; wall calcareous, moderately coarsely perforate; aperture a low and commonly asymmetrical, interiomarginal, umbilical-equatorial arch, parts of successive apertures may remain as relict supplementary apertures on one side of the test, the other side with accessory apertures opening into the posterior part of the chamber and bordered by a lip that is a continuation from that of the primary aperture.

	Pseudothalmanninella	Pseudothalmanninella klausi Pseudothalmanninella subticinensis Pseudothalmanninella tehamaensis Pseudothalmanninella ticinensis Pseudothalmanninella sp.
	Rotalipora Test trochospiral, biconvex to planoconvex, umbilicate, chambers angular to rhomboid in edge view, sutures elevated, curved, oblique on the spiral side, depressed to flush, straight to curved and radial on the umbilical side, periphery angular with a single keel, peripheral outline entire to lobulate; wall calcareous, finely and densely perforate, optically radial, surface smooth to pustulose, sutures may be thickened to beaded; aperture interiomarginal, extraumbilical-umbilical, bordered by a narrow to wide imperforate lip, accessory apertures along the sutural margin formed by an umbilical flaplike extension from the chamber and bordered by a narrow imperforate lip.
