Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. H. Erwin et al. 2011 | Erniettomorphs are a monophyletic clade of modular organisms in which the modules are smooth, unbranched, and cylindrical in shape. Several taxa are multi-foliate, meaning three or more identical leaf-like petaloids composed of modular tubes are arranged around a central axis. Tubes typically alternate from side to side along the central midline, implying that they are not truly bilaterally symmetrical. Growth results from sequentially adding modular segments that are approximately the same size and shape. |
