A crown-group cnidarian from the Ediacaran of Charnwood Forest, UK

Auroralumina preserves two bifurcating polyps in a rigid organic skeleton with tentacle impressions; a morphology analysis places it within crown Cnidaria.

Auroralumina was placed within crown Cnidaria in one morphology analysis; the profile retains that as a hypothesis rather than an ancestor claim.

The profile represents one Charnwood Forest fossil surface and does not infer a global Ediacaran cnidarian distribution.

Tentaculate polyps support a sessile feeding interpretation, while prey, colony physiology and habitat preference remain unobserved.

BGS GSM 105875 preserves two bifurcating polyp-like tubes, a rigid organic skeleton and tentacle impressions around the apertures.

The 562–557 Ma interval is the bounded Bradgate Formation context of one specimen, not a cnidarian crown age or global taxon range.

The Cnidaria root display uses 562–0 Ma as a sampled navigation envelope from the older bound of the 562–557 Ma Auroralumina horizon to living cnidarians; the fossil's crown placement is a morphology-analysis result, not the observed origin of Cnidaria.

Medusozoa is displayed at 562–0 Ma only as a stem-fossil-to-living navigation anthology: Auroralumina provides a matrix-dependent Ediacaran stem-medusozoan anchor, not a crown-Medusozoa FAD, direct ancestor or continuous global range.
