Neoceti is used for the sampled crown-whale branch joining Mysticeti and Odontoceti in the synthesis; the Eocene–Oligocene timing discussed there combines fossil and model evidence and is not a direct observation of the crown split. This navigation entry is not a phylogeny or a complete taxon dossier.

neoceti is displayed at 36–0 Ma only as a synthesis-bounded crown-whale navigation envelope, not a directly observed crown split. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.

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