Biology:Calcivertellidae

From HandWiki

Calcivertellidae is a family of foraminifera belonging to the order Miliolida.[1][2][3] Calcivertellids have been found in Pennsylvanian[4] to Triassic[5] beds and had a cosmopolitan distribution.[5][6]

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.[7][8]
