Diagnosis
ReferenceDiagnosis
A. R. Loeblich and H. Tappan 1984Test planispirally to trochospirally enrolled; chambers commonly with internal partition related to apertural foramen; wall of hyaline perforate, ultrastructurally and optically radiate aragonite (orthorhombic crystal form of calcium carbonate), the hexagonal prisms with c-axis normal to the wall surface, and basal pinacoid parallel to the surface, prisms in bundles surrounded by organic sheaths; extremely fine wall perforations may be localized in pore fields. M. Triassic to Holocene.
Remarks: The hyaline perforate, optically radiate aragonitic wall characterizes taxa of this suborder.
