Family STAFFELLIDAE A. D. Miklukho-Maklay, 1949

Tests planispiral, involute, lenticular or spherical, very rarely subfusiform, small to medium-sized. The septa remain planar during all the history of the group (in contrast to the other order, Fusulinida ). Chomata are often present but poorly developed. Some structures confused with parachomata are occasionally described. Wall calcareous secreted, initially aragonitic (probably fibrous and finely perforated?), then neomicrosparitized from aragonite. Aperture always simple, terminal and basal. Bashkirian (Early Pennsylvanian) to Changhsingian (latest Permian).
