Calcivertellinae is a subfamily of foraminifera belonging to the order Miliolida.[1][2] Calcivertellids have been found in Pennsylvanian[3] to Triassic[4] beds and had a cosmopolitan distribution.[4][5]

The calcivertellids are characterized by a porcelain-like test consisting of a single tube, initially forming a spiral but opening out into a zigzag shape. They live attached to a surface or to other organisms.[6][7]
