Figure 105 - Phylogenetic hypothesis for heterodontosaurids based on character data assembled in this study. Consensus tree summarizing 6 minimum-length trees (38 steps) based on maximum parsimony analysis of 30 characters in 8 heterodontosaurid genera (consistency index = 0.79; retention index = 0.88; Appendix I). Outgroups (constrained as shown) include basal saurischians (Eoraptor, Eodromaeus) and representative ornithischians (Lesothosaurus, Thyreophora, Neornithischia). Dashed lines indicate loss of resolution with an increase of one step in tree length; numbers at nodes indicate the decay index when four poorly known heterodontosaurids (Echinodon, Fruitadens, Lycorhinus, Pegomastax) are removed from the analysis. Red text highlights heterodontosaurid genera; arrows indicate stem-based definitions for Heterodontosauridae and Heterodontosaurinae; body icons of Tianyulong and Heterodontosaurus are shown at appropriate relative size (based on Figures 30 and 72).
