[2] When the fossil was first described in 2005, it was said to be most morphologically similar to Early Cretaceous members of Iguanodontidae, as opposed to later taxa such as Rhabdodon.
[2] Madzia et al. (2017), the study which named the genus, ran two phylogenetic analyses to test the relationships of the taxon.
The first, based on the matrix of MacDonald et al. (2012), found it within the clade Rhabdodontomorpha, with support very strong for it being outside of Ankylopollexia.
The analysis based on the Boyd et al. (2015) matrix, which they considered more strongly supported, due to better taxon sampling of basal ornithopods and neornithischians, found it to be one of the most basal ornithopods, sister to the clade Iguanodontia.
Their cladogram is reproduced below:[1] Hypsilophodon Marginocephalia Gideonmantellia Elasmaria Burianosaurus Muttaburrasaurus Rhabdodontidae Tenontosaurus Dryosauridae Camptosaurus Iguanodon Ouranosaurus
