A high-resolution growth series of Tyrannosaurus rex obtained from multiple lines of evidence Author Carr, Thomas D. Department of Biology, Carthage College, Kenosha, WI, USA text PeerJ 2020 8 e 9192 e 9192 journal article 224105 10.7717/peerj.9192 d363523c-cf93-410c-808d-0da6b8d62ff6 5824972

Table 6 Diagnostic characters of the juvenile growth category 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. PHYLO, corresponding homologous phylogenetic character (see Data S1).
