Table 9 Diagnostic characters of the adult and senescent growth categories of Tyrannosaurus rex. These characters are unambiguously optimized on the topology and have a consistency index (CI) of 1.0 indicating that they have changed only once on the ontogram and so can be considered diagnostic of the growth category. The last row corresponds to the senescent adult character. PHYLO, corresponding homologous phylogenetic character (see Data S1).| Character | Growth change |
