A multilocus, fossil-calibrated ray-finned-fish tree recovers living gars and bowfin together as Holostei. The result supports sampled holostean topology; its node age is model-dependent and not a direct fossil origin date.

Claim ledger
The 2024 analysis estimated crown Holostei between 303.82 and 271.33 Ma; this is a molecular-clock interval, not a fossil first appearance or a claim that sampled taxa span every intervening age.

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