Amphicyonidae

Expanded early-amphicyonid morphology sampling recovers Amphicyonidae as a basal caniform branch outside Canoidea, while exact sister relationships remain unresolved; the family is not a dog–bear ancestor blend or one linear lineage. This navigation entry is not a phylogeny or a complete taxon dossier.

Amphicyonidae navigation display is displayed at 42–1.8 Ma only as the source-bounded family sample, not a continuous global range or direct dog–bear ancestry. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.
