Figure 5.5. Phylogeny of the Theropoda, primarily after Holtr (2000), with outgroups as in Figure 5.1. Dotted lines show alternate phylogenetic positions for Fienerasaurus and Troodon. The letter A marks taxa with an arctometatarsus. The diets of theropods and other taxa on the cladogram are designated according to the following conventions: C Camivory H Herbivory ? Equivocal diet
