Their remains have been recovered in Asia, Europe, Africa and the Americas. Many primitive hadrosauroids, such as the Asian ''[Probactrosaurus](/source/Probactrosaurus)'' and ''[Altirhinus](/source/Altirhinus)'', have traditionally been included in a [paraphyletic](/source/paraphyly) (unnatural grouping) "[Iguanodontidae](/source/Iguanodontidae)". With [cladistic](/source/cladistics) analysis, the traditional Iguanodontidae has been largely disbanded, and probably includes only ''Iguanodon'' and perhaps its closest relatives. ==Classification== Hadrosauroidea was given a formal phylogenetic definition in the ''[PhyloCode](/source/PhyloCode)'' by Daniel Madzia and colleagues in 2021 as "the largest clade containing ''[Hadrosaurus foulkii](/source/Hadrosaurus_foulkii)'', but not ''[Iguanodon bernissartensis](/source/Iguanodon_bernissartensis)''".{{cite journal |last1=Madzia |first1=D. |last2=Arbour |first2=V.M. |last3=Boyd |first3=C.A. |last4=Farke |first4=A.A. |last5=Cruzado-Caballero |first5=P. |last6=Evans |first6=D.C. |title=The phylogenetic nomenclature of ornithischian dinosaurs |journal=PeerJ |date=2021 |volume=9 |article-number=e12362 |doi=10.7717/peerj.12362|doi-access=free |pmid=34966571 |pmc=8667728 }} The [cladogram](/source/cladogram) below follows an analysis by Andrew McDonald, 2012, and shows the position of Hadrosauroidea within Styracosterna:{{Cite journal | last1 = McDonald | first1 = A.
