The phylogenetic relationships of Tyrannosauroidea, based on parsimony analysis.
Strict consensus topology of five most parsimonious trees recovered from the cladistic analysis. Numbers by nodes indicate Bremer and jackknife support values. Thick lines next to each taxon depict temporal range, which in most cases is age uncertainty and not true range and colors of lines denote geographic areas. Branches of the phylogeny are not scaled to time. Silhouettes are in relative proportion and scaled to total body length (T. rex = 13 meters). Geographic silhouettes from Loewen et al.13 and taxon silhouettes from phylopic.org (Kileskus: T.M. Keesey; Guanlong: S. Hartman; Yutyrannus: S. Hartman; Dilong: FunkMonk; Juratyrant: S. Hartman, T.M. Keesey; Eotyrannus: S. Hartman; Dryptosaurus T.M. Keesey; Albertosaurus C. Dylke; Nanuqsaurus J. Headden; Daspletosaurus S. O’Connor, T.M. Keesey; Tyrannosaurus S. Hartman).
