As most of its features were described recently, as of early 2006, Amurosaurus has only been subjected to one cladistic analysis, which placed it as a basal member of the lambeosaurine subfamily of hadrosaurs, but more derived than either Tsintaosaurus or Jaxartosaurus.
Trots att de flesta av dessa drag beskrevs nyligen, i början av 2006, har Amurosaurus bara varit föremål för en kladistisk analys, vilken placerade den som en basal medlem av underfamiljen lambeosaurine i familjen hadrosaurier, men mer derived än antingen Tsintaosaurus eller Jaxartosaurus.
