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

BGS GSM 105875 preserves two bifurcating polyp-like tubes with tentacle impressions in a rigid organic skeleton and tests a crown-cnidarian interpretation.

Claim ledger
The profile represents one Charnwood Forest fossil surface and does not infer a global Ediacaran cnidarian distribution.
claim:taxon:auroralumina:biogeographyTentaculate polyps support a sessile feeding interpretation, while prey, colony physiology and habitat preference remain unobserved.
claim:taxon:auroralumina:ecologyBGS GSM 105875 preserves two bifurcating polyp-like tubes, a rigid organic skeleton and tentacle impressions around the apertures.
claim:taxon:auroralumina:morphologyThe 562–557 Ma interval is the bounded Bradgate Formation context of one specimen, not a cnidarian crown age or global taxon range.
claim:taxon:auroralumina:fossil-rangeKnown limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
