Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. D. Brasier et al. 2012 | Frond unipolar, with subsidiary growth tips present in mature specimens, at the distal ends of large first-order branches (Figs 6C–D and 8F). First- to second-order branches tend to be distally inflated. First-order branches comprise two rows of second-order branches with the freedom to overlap and rotate. First-order branches arranged in radiating series, alternating along a furled central axis. Towards their bases (and often in juvenile stages), first- to second-order branches typically furled and sometimes rotated, but rangeomorph elements become progressively displayed and unfurled in the direc- tion of growth (Fig. 6D). A basal disc is not confirmed. |
