}A phylogenetic analysis finds relationships amongst basal ornithopods to be extremely poorly resolved, but supports a sister‐group relationship between Changchunsaurus and Jeholosaurus shangyuanensis and suggests that an endemic clade of small‐bodied bipedal ornathopods existed in north‐east China during the Early to ‘middle’ Cretaceous.
