Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. J. Noble and J. Maletz 2000 | Test composed of a latticed shell formed by the coalescence of two or more rotasphaerid structures on ei- ther a single shell (cortical shell), or on the medullary shell in taxa with two shells. Each rotasphaerid structure consists of a primary spine more or less perpendicular to five or more rods which radiate from its base in a spoke-like fashion. The rods co- alesce from individual rotasphaerid structures to form a coarse latticed network of large polygonal pore frames. Pore frame- work is further subdivided by the development of secondary rods that connect the primary rods together. |
