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.
