Hadrosauridae is represented by the taxa and areas sampled in Prieto-Márquez’s event-based historical-biogeographic analysis; inferred dispersal routes are model results, not observed migrations or a complete global range.
claim:taxon:hadrosauridaeHadrosauridae
Hadrosauridae is displayed at 100.5–66 Ma only as the source's global historical-biogeography sample, not an exhaustive family record 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. This navigation entry is not a phylogeny or a complete taxon dossier.

- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
