Globigerinoidea is a superfamily of free-living, calcareous, planktonic foraminiferal protists that have lived in the open ocean since the Eocene. It is part of the suborder Globigerinina.
Tests are trochospiral but later chambers may be enveloping. walls are perforate with numerous small pores or fewer larger ones and the surface may be covered with narrow elongate monocrystalline spines. Apertures vary in position from interiomarginal to equatorial and may be relatively large. Secondary apertures along the sutures may also be found. Two families are included, the Globigerinidae and Hastigerinidae.
