Phylogenetic systematics of the Hesperocyoninae (Carnivora: Canidae)

A monographic morphology analysis samples Hesperocyon within the extinct Hesperocyoninae radiation of Canidae and revises species-level relationships across that record; the genus is not treated as a demonstrated direct ancestor of later canids.

Wang's monographic revision treats Hesperocyon as part of the extinct Hesperocyoninae canid sample and tests species-level relationships from scored morphology; the sampled genus is not asserted to be a direct ancestor of later canids.

This profile is limited to North American Hesperocyoninae localities assembled in Wang's monograph and does not turn that curated fossil sample into a complete genus distribution or origin-centre claim.

The Hesperocyon revision scores dental and cranial characters from named fossil material in a morphology matrix; those observed characters do not by themselves establish locomotor performance or a universal early-canid body plan.

The cited systematic monograph does not directly measure diet, habitual habitat, locomotor performance, body-size range or a single ecological guild for Hesperocyon, so those profile fields remain explicitly unresolved.

Hesperocyon navigation display is displayed at 40–29 Ma only as the monograph's sampled genus record, not exact global origination or extinction. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.
