Hedbergella
''Hedbergella'' is an extinct genus of planktonic foraminifera from the Cretaceous, described by Alfred R. Loeblich Jr, Loeblich and Helen Niña Tappan Loeblich, Tappan, 1961, as: Test free, trochospiral, biconvex, umbilicate, periphery rounded with no indication of keel or poreless margin; chambers globular to ovate; sutures depressed, radial, straight or curved; wall calcareous, finely perforate, radial in structure, surface smooth to hispid or rugose; aperture an interiomarginal, extraumbilical-umbilical arch commonly bordered above by a narrow lip or spatulate flap, ... Includes species otherwise similar to ''Praeglobotruncana'' but which lack a keel or poreless margin, hence is regarded as a separate genus rather than as a subgenus of ''Praeglobotruncana'' as by Banner and Blow (1959). ''Hedbergella'' was named by Brönnimann and Brown in 1958, and is included in the family Hedbergellidae and the suborder Globigerinina. ''Hedbergella'' ranges through most of the Cretaceous, ...
