Mysticeti is treated as the baleen-whale branch of sampled Neoceti, with toothed stem forms and later baleen-bearing lineages documenting a mosaic rather than an instantaneous transformation or one direct ancestor.

Mysticeti is treated as the baleen-whale branch of sampled Neoceti, with toothed stem forms and later baleen-bearing lineages documenting a mosaic rather than an instantaneous transformation or one direct ancestor. This navigation entry is not a phylogeny or a complete taxon dossier.

Claim ledger
mysticeti is displayed at 34–0 Ma only as the review's sampled stem-to-living mysticete envelope, not an exact clade origin. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.
claim:taxon:mysticeti:source-bounded-range-rc49Known limits
- 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.
