Figure 42 in Scelidosaurus harrisonii (Dinosauria: Ornithischia) from the Early Jurassic of Dorset, England: biology and phylogenetic relationships

Figure 42. Taxon deletion tree. Kunbarrasaurus and Jinyunpelta have been deleted. Tree length (of the 6 MPTs) is 212 steps, 14 steps fewer than found in the MPTs of the original dataset (Fig. 39). The principal clades: THYREOPHORA, STEGOSAURIA, ANKYLOSAURIA, Nodosauridae and Ankylosauridae conform topographically with those established by previous analyses. However, the ankylosauromorph branch and its composition, if confirmed in subsequent analyses, implies that the way Sereno (1986, et seq.) envisioned Eurypoda and Thyreophoroidea are meaningless.
