FIGURE 1. Phylogenetic relationships among theropods and (inset) within Tyrannosauridae as applied herein. Theropod phylogeny based largely on Sereno (1997, 2001) and Norell et al. (2001); uncertain placement of Herrerasauridae reflects information from Langer (2001), and unresolved "Ceratosauria" is based on Carrano and Sampson (1999). Tyrannosauroid phylogeny based on Currie (2000) and Holtz (2001a).
