Mitochondrial sequences test relationships among sampled neopterygians and recover a conditional topology with uneven node support. The limited extant sample does not delimit Neopterygii's fossil range, exact origin or direct ancestors. This navigation entry is not a phylogeny or a complete taxon dossier.

claim:taxon:neopterygiidivergence-time · medium
The 2024 clock analysis estimated crown Neopterygii between 331.33 and 312.76 Ma; the interval is a calibrated model result, not a fossil FAD or exact lineage duration.

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