Table 19 Data used in the correlation test between ontogeny and phylogeny for Tyrannosaurus rex. Phylogenetic topology of Carr et al. (2017) was followed for clade ranks. Boldfaced column gives the means for tied ranks (i.e., midranks). The category “ derived tyrannosaurines ” (i.e., Lythronax, Nanuqsaurus, Teratophoneus) occurs three times given the presence of three ontogenetic characters recovered in the ontogram that are homologous with corresponding synapomorphies. The 12th growth stage occurs twice given that two synontomorphies occr at that growth stage but their homologs occur at different internodes on the phylogenetic hierarchy. Boldface indicates the ranks used in the correlation test.| Clade | Clade rank | Clade midranks | Growth stage | Growth rank | Growth midranks |
