Representative
dinosaurs of the Hadrosauroideasuperfamily. The
familyHadrosauridae contains the dinosaurs commonly known as "duck-billed" dinosaurs. They were ubiquitous
herbivores during the
Cretaceous period, and prey to
theropoda such as Tyrannosaurus. The individual drawings represent typical
genera. All these groups were alive in the late Cretaceous, and are generally known only from a single fossil site. Animals are shown to scale.Image credit:
