I rather suspect that hadrosaurs were only quadrupedal in *slow*
locomotion, as when feeding or migrating. Based on their anatomy, when
greater speed was called for I suspect they pulled their arms back and ran
Such switching modality is known in living forms. Many lizards run
bipedally, and kangaroos have *three* modes: "pentapodal", quadrupedal, and
bipedal, depending on speed.
