Dinosaur Hall - Iguanodont
Probactrosaurus
Probactrosaurus is an “iguanodont” dinosaur from the Late
Cretaceous in Inner Mongolia, China. Probactrosaurus, or a form close
to it, gave rise to the hadrosaurs, “duck-billed” dinosaurs, that populated
much of latest Cretaceous Western North America and Asia. Probactrosaurus
lived about 95 million years ago. At about the same time, other iguanodonts
roamed the Western interior of the United States, including Arizona.
