This phylogeny is the author's opinion based on their interpretation of the literature. It is however, broadly congruent with recent works (e.g. Wilson, 2002; Upchurch et al., 2004; Upchurch et al., 2007; Yates, 2007; Carbillado et al., 2011; Whitlock, 2011; Mannion et al., 2013; Tschopp et al., 2015).

Based roughly on Mike Keesey's old Dinosauricon site. Beta and Gamma are sister taxa within the clade Alpha Delta is within Gamma, but not a member of Zeta. Epsilon, however, is Gamma incertae sedis. Eta is only tentatively placed within Zeta. Nomina nuda are non-italicized and placed in quotation marks, while unpublished taxa (as recognized by the ICZN) are designated the same way, but followed by an asterisk. Nomina dubia are not distinguished from valid taxa, as which taxa are indeterminate is a subjective question. Taxa in parentheses are technically valid according to the ICZN but not used by most theropod workers.
