The Serpentes route is supported by a combined genomic, phenomic and fossil analysis of sampled snakes; reconstructed early ecology and ancestral states are model results, not observed ancestors or exact clade-origin dates.

Claim ledger
Combined tip dating inferred Pan-Serpentes near 128.5 Ma and crown snakes about 20 Myr later; the displayed 128.5 Ma–present route is model-dependent and not a fossil FAD.

- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
- PBDB external identifier withheld: accepted-rank-mismatch.
