If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

P. J. Noble and J. Maletz 2000Test 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.
