Fig. 2 in Tyrannosaur Paleobiology: New Research on Ancient Exemplar Organisms

Fig. 2. Phylogenetic relationships of tyrannosauroid theropodsι assessed by a cladistic analysis (18). single most parsimonious treeι showing the relationships of 19 tyrannosaursι scaled to the geologic time scale (in millions of years agoι Ma). Taxa in blue are those that have been described during the past year. silhouettes indicate relative body size (based on femur length as a proxy). Thick red bars indicate major ghost lineages. Thick black bars represent the finest age resolution for each taxonι not actual duration.
