Fig. 3. Hypothesized phylogenetic position of CAGS−IG−04−CM−007, based on a parsimony analysis of three nonavian theropod outgroups and 20 avian ingroup taxa in PAUP* 4.0b10 (Swofford 2002). Numbered nodes are as follows: 1, Aves; 2, Pygostylia; 3, Confuciusornithidae; 4, Ornithothoraces; 5, Ornithuromorpha; 6, Ornithurae; 7, Carinatae; 8, Enantiornithes; 9, Euenantiornithes. Note the position of CAGS−IG−04−CM−007 within Euenantiornithes, as opposed to that of another Changma specimen (CAGS−IG− 02−0901; You et al. 2005), as a putative basal enantiornithine.
