Description
Test free, trochospiral, plano-convex to biconvex, umbilicus filled by plug which may be broken out in preservation, chambers rounded to ovate in plan, may have smoothly rounded periphery or develop short, blunt peripheral spine on each chamber partially covered by umbilical flap: wall calcreous, perforate, radially built, rotaliid in structure, smooth or yariously ornamented with large solid spines or fine scattered spines or nodes; apertures on umbilical side, interiomarginal and extraumbilical-umbilical, with lip; internal "tooth plate" near umbilical and axial chamber wall, intercameral foramen narrow, elongate, commashaped or slitlike areal opening, consisting of portion of former aperture, roughly paralleling base of apertural face and restricted by tooth plate of following chamber. [Woodella is apparently synonymous with Pararotalia and the type-species W. granosa appears to be conspecific with Rotalia capdevilensis CUSHMAN & BERMUDEZ.]
