Pakicetidae

Pakicetidae is reviewed as a separately sampled early Eocene cetacean family represented by incomplete and composite material; its placement helps test early whale relationships but does not make the family a direct ancestral stage for all later whales. This navigation entry is not a phylogeny or a complete taxon dossier.

Represented range50–47 Ma

pakicetidae is displayed at 50–47 Ma only as the review's sampled pakicetid interval, not a linear ancestral stage or exact endpoints. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.
