Results of the phylogenetic analysis of choristodere interrelationships under parsimony. a Strict consensus topology from the analysis of the phylogenetic matrix under parsimony. Different most parsimonious subtrees b, c showing conflicting topologies within Neochoristodera, but consistent placement of Tchoiria spp. and Ikechosaurus spp. as early-diverging simoedosaurids and champsosaurids, respectively. Key clades highlighted (Champsosaurus in green, Kosmodraco in blue, and derived "allochoristoderes" in yellow). Champsosaurus silhouette public domain from phylopic.org
