Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. H. Erwin et al. 2011 | Triradialomorphs (Trilobozoa?) are a monophyletic clade characterized by three plains of symmetry (Anfesta; Triforillonia) or by the spiral rotation of three independent arm-like structures (Tribrachidium, Albumares). Each branch is typically composed of smaller branching structures. |
