The 55–0 Ma Whippomorpha route uses a rounded early Eocene navigation ceiling and combines the approximately 48.6 Ma Indohyus raoellid sample with living whale–hippo retroposon topology; neither source dates the Whippomorpha crown, and the span is not a direct lineage duration. This navigation entry is not a phylogeny or a complete taxon dossier.
