Claim ledger
Staurozoa has no supported scalar crown range in the cited evidence: extant systematics does not date the crown and the Haootia comparison is contested, so the former 562–0 Ma display is withheld.

- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
