Daughter taxa (time control age-window is: 0-800Ma) | ||||
Ciperoella anguliofficinalis Like C. ciperoensis but less lobulate peripheral outline, more compact form and a greater rate of chamber size increase | ||||

Ciperoella ciperoensis Test low trochospiral, globular, lobulate, umbilicus open; 5 chambers in final whorl; aperture umbilical; | ||||
Ciperoella fariasi Like C. ciperoensis but with larger, more globular, test, larger umbilicus and higher trochospire. | ||||
Ciperoella sp. |
