Fig. 2. Cladogram of Theropoda modifed from Carrano et al. (2012). Thickened branches indicate lineages possessing the dentary groove, thin branches indicate lineages in which the groove is absent. Grayed-out braches marked with dashed lines indicate taxa without a known dentary. Circled numbers indicate sequence of losses of the dentary groove assuming maximum parsimony.
